Cat Health Checklist: From Kitten to Senior Cat

1KAHU Editorial Team
Cat Health Checklist: From Kitten to Senior Cat

A cat's health priorities change throughout life. Kittens need particular attention to growth, vaccination, infectious-disease risk, nutrition and healthy behavioural development. Young and mature adult cats still need regular preventive veterinary care, with ongoing monitoring of weight, body condition, dental health, elimination, behaviour and lifestyle risks. Senior cats—defined in AAHA/AAFP guidance as cats over 10 years—benefit from closer monitoring because changes in appetite, drinking, urination, weight, mobility, grooming, vision or behaviour may be early signs of disease.

Cats are very good at being cats.

They are often less good at telling us clearly when something is wrong.

A dog may stop wanting to walk.

A cat may simply stop jumping onto one particular shelf.

A dog may visibly limp.

A cat may sleep somewhere different because climbing onto the usual bed has become uncomfortable.

A cat may still eat, but eat a little less.

Still use the litter tray, but visit it more often.

Still groom, but stop reaching the lower back.

These changes can be subtle.

That is why preventive feline healthcare is not only about asking:

“Does my cat look sick?”

It is about knowing:

“What is normal for this cat, and has something changed?”

The 2021 AAHA/AAFP Feline Life Stage Guidelines divide feline life into four main age-related stages:

  • Kitten: birth to under 1 year
  • Young adult: 1–6 years
  • Mature adult: 7–10 years
  • Senior: over 10 years

The guidelines emphasise that healthcare should evolve with the cat's life stage rather than remain the same throughout life.

This checklist helps you understand what to monitor from kittenhood through the senior years.

It is not designed to diagnose disease at home.

It is designed to make important changes harder to miss.

Key takeaways

  • Every cat should receive regular preventive veterinary examinations, including apparently healthy indoor cats.
  • AAHA/AAFP recommends at least annual examinations for cats generally and at least every six months for senior cats.
  • A cat's health record should track weight, body condition and muscle condition, not weight alone.
  • Dental care should begin during kittenhood and continue throughout life.
  • Elimination habits are an important health signal; changes in urination or defecation should not automatically be treated as behavioural problems.
  • Mature and senior cats deserve increasing attention to appetite, thirst, urination, mobility, grooming, vision, behaviour and masses.
  • Senior-cat behavioural changes may sometimes reflect pain, sensory loss, metabolic disease or cognitive decline rather than simply “old age.”
  • AAHA/AAFP recommends progressively more structured diagnostic screening as cats age, with senior cats receiving at least yearly testing and six-monthly testing recommended in its guideline framework.
  • A cat can appear outwardly well while gradual trends in weight, kidney markers, thyroid values, blood pressure or urine concentration are changing.
  • The most useful health record is not a snapshot. It is a timeline.

Why cats benefit from regular preventive care

Cats can mask or compensate for illness remarkably well.

That does not mean they do not become ill.

It means the first visible signs may be subtle.

AAHA/AAFP recommends at least annual veterinary examinations for cats of all life stages, with more frequent visits for senior cats.

A routine veterinary examination can include assessment of:

  • body weight;
  • body condition;
  • muscle condition;
  • teeth and mouth;
  • heart and lungs;
  • abdomen;
  • skin;
  • eyes;
  • musculoskeletal system;
  • behaviour;
  • pain;
  • lifestyle;
  • nutrition.

Preventive care is therefore not simply:

“annual vaccination.”

It is:

“regular reassessment of the whole cat.”

Kitten health checklist

AAHA/AAFP defines the kitten stage as:

birth to under one year.

This period involves extraordinary change.

A kitten is:

  • growing rapidly;
  • developing behaviourally;
  • establishing eating habits;
  • learning about the environment;
  • completing vaccination;
  • developing permanent teeth;
  • encountering new infectious-disease risks.

The health plan should reflect that.

1. Arrange an early veterinary examination

The first veterinary visits establish a baseline.

The veterinarian may assess:

  • weight;
  • growth;
  • heart;
  • lungs;
  • eyes;
  • ears;
  • mouth;
  • dentition;
  • abdomen;
  • skin;
  • musculoskeletal development;
  • congenital abnormalities;
  • infectious-disease risk.

AAHA/AAFP specifically identifies congenital/genetic findings, infectious disease and dental development as important kitten-stage considerations.

Bring:

  • breeder/rescue records;
  • vaccination history;
  • parasite history;
  • microchip information;
  • previous test results.

2. Complete the vaccination plan

Kitten vaccination commonly includes core protection against:

  • feline panleukopenia virus;
  • feline herpesvirus-1;
  • feline calicivirus.

FeLV and rabies also require consideration according to age, risk, geography and local law.

The exact schedule should come from the veterinary team.

Related guide: Kitten Vaccination Schedule: A Complete Guide

3. Discuss FeLV and FIV testing

AAHA/AAFP's diagnostic framework strongly recommends retroviral testing during the kitten life stage.

The appropriate testing approach depends on:

  • kitten origin;
  • previous exposure;
  • household cats;
  • health;
  • testing history.

Keep the result in the medical record.

Do not confuse:

FeLV testing

with

FeLV vaccination.

They serve different purposes.

4. Discuss parasite risk

Parasite risk depends heavily on:

  • geography;
  • household;
  • outdoor access;
  • prey exposure;
  • other animals;
  • travel.

AAHA/AAFP also strongly recommends faecal testing as part of its kitten diagnostic framework.

Your veterinarian should determine which:

  • tests;
  • treatments;
  • preventive products

are appropriate.

Never assume a dog parasite product is safe for a cat.

5. Track growth

Kittens change quickly.

Record weight over time.

A single weight tells you:

what the kitten weighs today.

A series tells you:

how the kitten is growing.

AAHA's nutrition guidelines recommend including:

  • body weight;
  • body condition score;
  • muscle condition score

in routine nutritional assessment.

6. Feed for growth

Kittens require nutrition appropriate to growth.

The correct amount depends on factors including:

  • age;
  • body condition;
  • activity;
  • health;
  • food energy density.

Do not assume the packet feeding guide is permanently correct for the individual kitten.

Reassess as growth changes.

7. Monitor appetite carefully

Kittens can become unwell relatively quickly.

Know:

  • normal meal pattern;
  • food preference;
  • approximate intake.

A persistent or marked reduction in appetite, particularly with:

  • vomiting;
  • diarrhoea;
  • lethargy;
  • weakness

deserves prompt veterinary advice.

8. Monitor litter-box use

From the beginning, learn what is normal.

Notice:

  • urination frequency;
  • stool consistency;
  • straining;
  • accidents;
  • blood;
  • diarrhoea;
  • constipation.

Litter-box behaviour is health information.

Do not automatically interpret toileting changes as:

“bad behaviour.”

9. Monitor eyes and nose

Kittens can experience infectious upper respiratory disease.

Watch for:

  • eye discharge;
  • redness;
  • squinting;
  • nasal discharge;
  • repeated sneezing;
  • reduced appetite.

Persistent or severe symptoms warrant veterinary assessment.

10. Watch dental development

Kitten visits should include attention to:

  • deciduous teeth;
  • permanent teeth;
  • bite;
  • retained teeth;
  • oral health.

AAHA's feline life-stage guidance recommends establishing lifelong dental care beginning with kitten visits.

Start positive handling around the mouth early.

11. Establish healthy behaviour and enrichment

Feline health and behaviour are closely linked.

AAHA/AAFP emphasises that understanding normal feline behaviour is important throughout life for both welfare and prevention of behaviour problems.

A kitten should have access to:

  • play;
  • scratching;
  • hiding;
  • climbing;
  • resting;
  • social interaction;
  • choice.

Health is not only blood tests and vaccinations.

The environment matters too.

Young adult cat health checklist

AAHA/AAFP defines young adulthood as approximately:

1–6 years.

Many cats in this age group appear completely healthy.

That makes it easy to stop paying attention.

But this is precisely when preventive habits matter.

12. Maintain regular veterinary examinations

Even a healthy young adult cat should receive routine preventive assessment.

AAHA/AAFP recommends at least annual examinations.

Do not wait for obvious illness.

13. Watch weight closely

Cats can gain weight gradually.

Because guardians see their cats every day, slow changes can be difficult to notice.

AAHA recommends assessing:

  • weight;
  • BCS;
  • MCS

at veterinary examinations.

The scale alone is not enough.

A cat can:

  • gain fat;
  • lose muscle;
  • or both.

14. Learn body condition

In a cat at an ideal body condition, ribs should generally be palpable without excessive fat covering and a waist should be visible when viewed appropriately from above.

The veterinarian can show you how to assess this safely.

Do not wait until:

“My cat looks obviously obese.”

Weight problems are easier to address before they become severe.

15. Track what your cat actually eats

A nutrition history should include more than the main food.

AAHA recommends considering:

  • meals;
  • treats;
  • table foods;
  • supplements;
  • foods used for medication

when evaluating nutritional intake.

That matters especially in multi-cat homes where it may be difficult to know who is eating what.

16. Monitor vomiting

Occasional vomiting is sometimes dismissed as:

“cats just do that.”

Do not normalise persistent vomiting.

AAHA/AAFP specifically recommends asking young-adult guardians about:

  • vomiting;
  • hairball-associated vomiting;
  • diarrhoea.

Record:

  • frequency;
  • timing;
  • appearance;
  • appetite;
  • weight;
  • stool.

Repeated vomiting deserves veterinary discussion.

17. Monitor grooming habits

Changes in grooming may be clinically relevant.

AAHA/AAFP explicitly includes grooming change as something to ask about in young, mature and senior adult cats.

Possible changes include:

  • overgrooming;
  • hair loss;
  • matting;
  • greasy coat;
  • reduced grooming;
  • repeated licking of one area.

These can relate to:

  • skin disease;
  • pain;
  • stress;
  • mobility;
  • systemic illness.

18. Monitor behaviour

Know your cat's normal personality.

Watch for:

  • more hiding;
  • less interaction;
  • aggression;
  • reluctance to play;
  • changed sleep;
  • altered vocalisation;
  • anxiety.

Behavioural change can reflect:

  • environment;
  • stress;
  • pain;
  • disease.

Do not assume every behaviour problem is purely behavioural.

19. Continue dental care

AAHA recommends proactive lifelong dental care beginning in kittenhood.

In young adult cats, veterinary examinations should pay particular attention to:

  • periodontal disease;
  • tooth resorption;
  • oral pain.

Possible clues include:

  • bad breath;
  • drooling;
  • dropping food;
  • altered chewing;
  • reduced grooming;
  • pawing at the mouth;
  • food preference changes.

But significant dental disease can also exist with few obvious signs at home.

20. Reassess vaccination and lifestyle

A young adult cat's life may be different from kittenhood.

Ask:

  • Is the cat now outdoors?
  • Has another cat joined the household?
  • Does the cat board?
  • Is the cat travelling?
  • Has FeLV exposure risk changed?

Vaccination should evolve with real exposure.

21. Establish baseline screening where appropriate

For apparently healthy young adult cats, AAHA/AAFP lists several diagnostic tests as considerations, generally recommending a baseline and then further testing according to individual need.

That may include consideration of:

  • CBC;
  • biochemistry;
  • urinalysis;
  • renal markers;
  • T4;
  • blood pressure;
  • retroviral testing.

This is not a universal DIY checklist of tests every one-year-old cat must receive.

Your veterinarian should determine what is appropriate.

Mature adult cat health checklist

AAHA/AAFP defines the mature adult stage as:

7–10 years.

This is an important transition.

The cat may still look and behave young.

But the likelihood of several age-associated diseases begins to increase.

Preventive care should become more deliberate.

22. Monitor appetite changes

AAHA/AAFP specifically recommends asking mature-cat guardians about changes in appetite and hydration.

Notice:

  • eating less;
  • eating more;
  • new food selectivity;
  • difficulty eating;
  • seeking food unusually often.

Both:

reduced appetite

and

increased appetite

can matter.

23. Monitor drinking

Cats do not always make thirst changes obvious.

Notice whether you are:

  • filling bowls more often;
  • seeing more drinking;
  • finding the cat at taps;
  • noticing larger urine clumps.

AAHA/AAFP specifically highlights changes in hydration, urination and thirst at the mature and senior stages.

24. Watch urine output and litter-box behaviour

Changes may include:

  • more urine;
  • less urine;
  • frequent visits;
  • straining;
  • urinating outside the box.

These can be associated with very different medical conditions.

A cat repeatedly trying to urinate but producing little or no urine requires urgent veterinary assessment.

Male cats are at particular risk of life-threatening urethral obstruction.

Do not wait for a routine appointment if your cat appears unable to pass urine.

25. Watch for weight loss even if appetite is good

An important feline pattern is:

eating normally—or even eating more—while losing weight.

That deserves veterinary investigation.

Potential causes vary widely and cannot be diagnosed from the pattern alone.

A historical weight graph can make gradual loss visible much earlier.

26. Monitor muscle condition

Muscle loss can occur without dramatic weight loss.

Look at:

  • spine;
  • hips;
  • shoulders;
  • skull.

AAHA's nutrition guidance recommends assessing muscle condition separately from body condition.

This becomes increasingly important as cats age.

27. Watch mobility carefully

Cats rarely announce:

“My joints hurt.”

Instead, you might notice:

  • hesitation before jumping;
  • jumping onto lower surfaces first;
  • no longer reaching a favourite shelf;
  • difficulty entering a high-sided litter box;
  • reduced play;
  • sleeping downstairs;
  • stiffness.

A cat who stops jumping may not simply be:

“getting sensible.”

Pain deserves consideration.

28. Watch grooming ability

Reduced grooming over:

  • lower back;
  • hips;
  • hindquarters

may indicate:

  • mobility problems;
  • pain;
  • obesity;
  • systemic disease.

Matting in a previously well-groomed cat is worth noticing.

29. Check for lumps

AAHA/AAFP recommends asking mature and senior cat guardians about masses.

Record:

  • location;
  • date noticed;
  • approximate size;
  • changes.

Do not diagnose a lump from appearance alone.

Mention new or changing masses to your veterinarian.

30. Increase attention to dental health

As cats age, chronic oral disease can become increasingly significant.

Persistent:

  • bad breath;
  • drooling;
  • chewing change;
  • reduced appetite;
  • weight loss;
  • food dropping

may warrant dental assessment.

Oral pain may be much less obvious than guardians expect.

31. Discuss more structured screening

AAHA/AAFP's guideline for apparently healthy mature adult cats recommends several diagnostic categories approximately every 1–2 years, depending on the individual.

These include recommendations for:

  • CBC;
  • serum biochemistry;
  • urinalysis;
  • T4;
  • kidney markers such as SDMA;
  • blood pressure.

The guidelines specifically note that longitudinal trends in:

  • creatinine;
  • SDMA;
  • T4;
  • blood pressure;
  • urine specific gravity

may help identify concerning changes over time.

This is exactly why keeping historical results matters.

Senior cat health checklist

AAHA/AAFP defines senior cats as:

over 10 years old.

Senior does not mean:

sick.

A healthy older cat may still:

  • play;
  • climb;
  • explore;
  • eat enthusiastically;
  • enjoy excellent quality of life.

But ageing increases the importance of detecting change early.

32. Consider veterinary examinations at least every six months

AAHA/AAFP recommends:

  • minimum annual examinations at all life stages;
  • at least every six months for senior cats.

A year is a significant period in the life of an older cat.

More frequent assessment can help identify trends that might otherwise remain invisible for a long time.

33. Expect more regular diagnostic screening

For apparently healthy senior cats, AAHA/AAFP strongly recommends regular:

  • CBC;
  • biochemistry;
  • urinalysis;
  • T4;
  • renal indices;
  • blood-pressure assessment.

The guideline recommends testing at least yearly, with every six months recommended.

This is a professional guideline framework.

It should not be interpreted as an instruction that every senior cat everywhere receives an identical panel at exactly the same interval.

Clinical history and veterinary judgement still matter.

Chronic kidney disease becomes increasingly relevant as cats age.

Do not try to diagnose kidney disease from drinking alone.

Instead, monitor:

  • weight;
  • appetite;
  • thirst;
  • urination;
  • vomiting;
  • energy

and let the veterinarian interpret these alongside:

  • examination;
  • blood tests;
  • urine tests;
  • blood pressure;
  • other diagnostics.

AAHA/AAFP specifically highlights longitudinal changes in creatinine, SDMA and urine specific gravity as examples of why repeated measurements can be useful.

Hyperthyroidism is an important condition in older cats.

Possible changes may include:

  • weight loss;
  • increased appetite;
  • increased activity;
  • vocalisation;
  • vomiting;
  • increased thirst.

But these signs are not specific.

AAHA/AAFP recommends T4 assessment as part of mature and senior diagnostic screening, with particular emphasis as cats age.

36. Monitor blood pressure

High blood pressure can occur in cats, particularly alongside some age-associated diseases.

It may not create obvious early signs.

AAHA/AAFP includes blood pressure in its mature and senior screening framework.

Severe hypertension can affect organs including:

  • eyes;
  • brain;
  • heart;
  • kidneys.

That makes screening more useful than waiting for obvious symptoms.

37. Monitor vision

AAHA/AAFP recommends asking mature and senior guardians about vision changes.

Possible signs include:

  • bumping into objects;
  • hesitation jumping;
  • disorientation;
  • reluctance in dim light;
  • apparent sudden blindness.

Sudden visual loss should be treated as urgent.

38. Monitor mobility and pain

Cats with arthritis or other pain may not limp dramatically.

Instead, look for:

  • lower jumps;
  • hesitation;
  • reduced grooming;
  • changed sleeping place;
  • difficulty using stairs;
  • difficulty entering litter trays;
  • irritability when touched.

Senior cats with mobility issues may benefit from environmental changes such as lower-entry litter trays and easier access to core resources.

39. Adapt litter-box access

A high-sided litter tray that worked perfectly at age four may be difficult at age fourteen.

AAHA/AAFP recommends considering:

  • lower box entry;
  • boxes close to core living areas;
  • avoiding unnecessary stairs

for older cats with mobility issues.

The cat has not necessarily:

“forgotten where the toilet is.”

The toilet may simply have become harder to use.

40. Watch for behavioural change

AAHA/AAFP advises that new or unusual behaviour in senior cats should be medically evaluated.

Changes might include:

  • nighttime vocalisation;
  • altered sleep;
  • confusion;
  • increased anxiety;
  • hiding;
  • clinginess;
  • aggression;
  • house-soiling.

These behaviours can occur with conditions including:

  • pain;
  • sensory decline;
  • hyperthyroidism;
  • hypertension;
  • cognitive dysfunction;
  • other disease.

Do not assume:

“She's just getting old.”

41. Watch nighttime vocalisation

Nighttime crying or vocalisation can be particularly noticeable in senior cats.

AAHA/AAFP notes that it may relate to:

  • hearing or visual decline;
  • cognitive change;
  • pain;
  • hyperthyroidism;
  • hypertension.

Record:

  • when it occurs;
  • frequency;
  • associated behaviour.

A short video may be useful to the veterinarian.

42. Monitor appetite closely

Senior cats can develop both:

  • reduced appetite;
  • increased appetite.

Persistent change deserves attention.

AAHA notes that older cats may also experience changes in energy requirements, body condition and digestive capacity, making nutritional assessment particularly important.

43. Do not assume senior cats need fewer calories

A common assumption is:

“Older = less active = always feed less.”

It is not universally true for cats.

AAHA notes that energy requirements may decline up to around age 10 but can increase again in some older cats, while reduced digestive capability and low body condition can also become concerns.

Feed the cat in front of you.

Not the age printed on the food bag.

44. Watch for muscle loss and low body condition

Being underweight can become an important problem in senior cats.

Track:

  • weight;
  • body condition;
  • muscle condition.

A cat can lose muscle gradually even while maintaining a superficially similar silhouette.

45. Review medication regularly

Older cats may receive long-term medications.

Keep a structured list containing:

  • medication name;
  • strength;
  • dose;
  • frequency;
  • reason;
  • prescribing veterinarian;
  • monitoring requirements.

Do not:

  • alter;
  • stop;
  • double;
  • restart

medication without appropriate veterinary guidance.

46. Think about quality of life

For older cats, monitoring should include more than disease values.

Ask:

  • Is the cat eating comfortably?
  • Can they reach food and water?
  • Can they use the litter box without difficulty?
  • Can they groom?
  • Can they rest comfortably?
  • Do they still interact?
  • Do they enjoy favourite activities?
  • Is pain controlled?
  • Are difficult days becoming more frequent?

AAHA/AAFP includes quality-of-life assessment among relevant considerations across feline care when clinically appropriate.

What should you monitor at home every week?

You do not need to conduct a veterinary examination.

Use a simple observational check.

APPETITE

  • Eating normally?
  • Eating more?
  • Eating less?

WATER

  • Drinking pattern unchanged?

LITTER

  • Urination normal?
  • Stool normal?
  • Any straining?
  • Any accidents?

MOVEMENT

  • Jumping normally?
  • Climbing normally?
  • Any stiffness?

GROOMING

  • Coat normal?
  • Grooming reduced?
  • Overgrooming?

BEHAVIOUR

  • Interaction normal?
  • Hiding more?
  • New vocalisation?
  • Sleep changed?

BODY

  • Any new lump?
  • Obvious weight change?
  • Any wounds?

FACE AND MOUTH

  • Eyes clear?
  • Nose normal?
  • Bad breath or drooling?

The central question is:

“Has anything changed from this cat's usual pattern?”

A monthly cat-health snapshot

A simple monthly record could include:

  • body weight where practical;
  • appetite;
  • drinking change;
  • litter habits;
  • vomiting episodes;
  • mobility;
  • grooming;
  • new masses;
  • medication changes.

You do not need a spreadsheet with fifty variables.

The objective is to make gradual change visible.

Why cats need trend-based health records

Imagine this record:

March — 5.1 kg

June — 4.9 kg

September — 4.6 kg

December — 4.3 kg

None of those individual weights necessarily looks dramatic.

The trend does.

Or:

January — occasional night vocalisation

March — increased night vocalisation

April — drinking more

May — weight loss noted

Again:

the individual observations may seem small.

Together, they form useful history.

What should be updated after every veterinary appointment?

Update:

Visit

  • Date
  • Practice
  • Veterinarian
  • Reason

Health

  • Weight
  • Body condition
  • Relevant muscle condition
  • Findings

Diagnostics

  • Blood tests
  • Urinalysis
  • Blood pressure
  • Imaging
  • Other tests

Treatment

  • Medication
  • Procedures

Preventive care

  • Vaccination
  • Parasite plan
  • Dental plan

Follow-up

  • Next appointment
  • Monitoring requirement

This is how a pet profile becomes clinically useful over time.

Cat health by life stage

Health area Kitten Young Adult Mature Adult Senior
Veterinary exams Frequent early care At least annually At least annually At least every 6 months
Vaccination Primary series Risk-based continuation Reassess lifestyle Individualised continuation
Weight Growth monitoring Prevent overweight Watch gain/loss Watch weight + muscle loss
Dental Build habits Periodontal/tooth-resorption focus Increasing importance Maintain comfort/function
Behaviour Development/enrichment Monitor change Monitor subtle change Behaviour may signal disease
Litter habits Establish baseline Monitor Increasing importance Accessibility + disease monitoring
Mobility Development/play Normal activity Watch jumping change Pain/mobility adaptation
Diagnostics Baseline/risk-based Baseline then as needed More structured At least yearly; 6-monthly recommended in AAHA/AAFP framework
Nutrition Growth Maintain ideal condition Prevent obesity + monitor change Preserve body and muscle condition

This is a life-stage framework, not an individual medical prescription.

Signs worth discussing with a veterinarian

Contact your veterinary practice if you notice meaningful or persistent changes such as:

  • reduced appetite;
  • increased appetite with weight loss;
  • unexplained weight change;
  • drinking more;
  • urinating more;
  • straining to urinate;
  • repeated vomiting;
  • persistent diarrhoea;
  • constipation;
  • difficulty jumping;
  • reduced grooming;
  • new lump;
  • altered breathing;
  • new hiding behaviour;
  • persistent vocalisation;
  • house-soiling;
  • eye changes;
  • apparent vision loss;
  • mouth pain;
  • severe bad breath.

The key point is:

change deserves context.

Not every change is an emergency.

But repeated or progressive change deserves attention.

When should you seek emergency veterinary care?

Seek urgent or emergency veterinary help for signs such as:

  • severe difficulty breathing;
  • collapse;
  • unresponsiveness;
  • seizures;
  • major trauma;
  • uncontrolled bleeding;
  • suspected poisoning;
  • repeated severe vomiting;
  • profound weakness;
  • significant abdominal pain;
  • sudden blindness;
  • repeated attempts to urinate with little or no urine.

For a cat—particularly a male cat—inability to pass urine can be life-threatening and should not be monitored at home waiting for it to resolve.

Do not let a symptom tracker, Academy article or AI conversation delay emergency care.

The product question should be:

“What has changed?”

not merely:

“What records exist?”

Product opportunity: normal baseline

For cats specifically, I would add an optional concept to the 1KAHU health profile:

My Cat's Normal

Guardian-defined baseline such as:

Appetite: very food-motivated

Water: rarely observed drinking

Litter: 2–3 urine clumps/day

Vomiting: rare

Activity: jumps to high shelf daily

Grooming: meticulous

Social: sleeps on guardian's bed

Vocalisation: quiet

Months later:

No longer jumping to shelf

is more meaningful because the platform knows it represents a change from baseline.

That aligns extremely well with feline medicine, where subtle behavioural and functional changes can matter.

Good:

“You've recorded that Luna's weight has decreased across her last three measurements and that she has recently been drinking more. These changes can have several causes and would be worth discussing with a veterinarian.”

Not good:

“Luna has kidney disease.”

Another appropriate example:

“You've recorded repeated attempts to urinate with little or no urine. This can be an emergency in cats, particularly males. Seek veterinary care immediately.”

Here the AI is not diagnosing.

It is:

recognising a high-risk pattern → escalating appropriately.

That distinction should be central to 1KAHU's clinical-safety design.

Key facts

Cats have four main age-related life stages in AAHA/AAFP guidance. Kitten is birth to under 1 year, young adult 1–6 years, mature adult 7–10 years and senior over 10 years.

All cats need preventive examinations. AAHA/AAFP recommends at least annual examinations and at least six-monthly examinations for seniors.

Weight alone is insufficient. Body condition and muscle condition should also be evaluated.

Dental care begins in kittenhood. AAHA recommends lifelong proactive dental care rather than waiting for obvious oral disease.

Changes in litter habits can be medical. Urinary, gastrointestinal, mobility and metabolic problems may all affect elimination behaviour.

Mature and senior cats require closer surveillance. Appetite, thirst, urination, mobility, vision, grooming, behaviour and masses become particularly important areas to monitor.

Senior behavioural changes deserve medical assessment. Nighttime vocalisation and other changes may relate to sensory decline, pain, hyperthyroidism, hypertension or cognitive dysfunction.

Diagnostic screening becomes more structured with age. AAHA/AAFP recommends mature-adult testing roughly every 1–2 years and senior testing at least yearly, with six-monthly testing recommended in its guideline framework.

Senior cats can lose weight and muscle. Older feline nutritional needs are variable, and being underweight can become an important concern.

Frequently asked questions

How often should my cat see a veterinarian?

AAHA/AAFP recommends a minimum of annual examinations for cats generally and at least every six months for senior cats. Individual health conditions may require more frequent care.

What age is a cat considered senior?

Under the 2021 AAHA/AAFP Feline Life Stage Guidelines, cats older than 10 years are classified as senior.

What should I regularly check on my cat?

Pay attention to appetite, drinking, urination, stool, vomiting, weight, movement, grooming, behaviour, eyes, mouth and litter-box habits. Changes from the individual cat's baseline are often more useful than isolated observations.

How often should I weigh my cat?

There is no single required home interval for every healthy cat. Weight should be recorded at veterinary visits, and more frequent monitoring can be useful when growth, obesity, weight loss, disease or senior status makes trends important.

Is vomiting normal in cats?

Occasional vomiting can occur, but repeated vomiting should not automatically be dismissed as normal. AAHA/AAFP specifically recommends discussing vomiting and hairball-associated vomiting in feline health histories.

My cat drinks more than before. Is that important?

Yes. A meaningful increase in drinking can accompany several conditions and is particularly relevant in mature and senior cats. Record the change and discuss it with your veterinarian.

Why is my cat suddenly urinating outside the litter box?

There are behavioural and environmental possibilities, but medical causes must also be considered. AAHA/AAFP notes that urinary disease, diabetes, chronic kidney disease, hyperthyroidism, constipation, pain and mobility problems may all contribute to elimination changes.

Is my older cat slowing down because of age?

Possibly, but pain and mobility problems can also cause reduced jumping or activity. Do not automatically assume movement change is normal ageing.

Should senior cats have blood tests?

AAHA/AAFP strongly recommends structured diagnostic screening in senior cats, including CBC, biochemistry, urinalysis, T4, renal indices and blood pressure, at least yearly and preferably approximately every six months within its guideline framework. Your veterinarian should individualise the plan.

Why does my senior cat cry at night?

Potential explanations include sensory changes, pain, hyperthyroidism, hypertension and cognitive dysfunction. AAHA/AAFP recommends medical assessment for new or unusual senior-cat behaviour.

Does an old cat automatically need senior food?

No. Diet should be based on the individual cat's body condition, muscle condition, health and nutritional requirements. AAHA notes that senior cats can have highly variable energy needs and may actually become underweight.

How can I tell if my cat has lost muscle?

Muscle loss can become visible around the spine, hips, shoulders and head. Veterinary assessment of muscle condition can help distinguish muscle loss from changes in body fat.

Should indoor cats still have annual health checks?

Yes. Being indoors changes some risks but does not prevent dental disease, obesity, kidney disease, thyroid disease, diabetes, pain or other health problems.

Why is tracking litter-box behaviour so important?

The litter box provides information about urination and defecation. Changes in frequency, volume, straining, consistency or location can be early indicators of health or environmental problems.

When is difficulty urinating an emergency?

A cat making repeated attempts to urinate while producing little or no urine needs urgent veterinary assessment. Urethral obstruction can become life-threatening, particularly in male cats.

Cats rarely send push notifications

They show change in smaller ways.

The bowl takes longer to empty.

The water bowl empties faster.

The litter clumps get larger.

The cat no longer jumps onto the wardrobe.

The coat looks slightly less groomed.

There is more sleeping downstairs.

A little more vocalisation at night.

A little less interaction.

One change can mean almost anything.

Several changes over time can create a very different picture.

That is why the most valuable cat-health record is not:

a collection of documents.

It is:

a history of the cat.

What they weighed.

How they ate.

How they moved.

How they behaved.

What the veterinarian found.

What changed.

And when.

From kittenhood to old age, the aim is not constant anxiety.

It is familiarity.

Because the guardian who knows:

“this is normal for my cat”

is much better positioned to notice:

“this is different.”

1KAHU

One health history for every stage of your cat's life.

A cat's health information can accumulate over many years:

Vaccinations

Weight

Veterinary Visits

Dental Care

Medication

Blood Tests

Urinalysis

Blood Pressure

Health Documents

Care Team

1KAHU is designed to connect those moments around one continuous pet profile.

From:

Kitten → Young Adult → Mature Adult → Senior

the history remains with the same cat.

That means guardians can see not simply:

“What happened at today's appointment?”

but:

“What has changed over the last five years?”

For feline health, that difference can be especially valuable.

Kitten Vaccination Schedule: A Complete Guide

Kitten vaccination usually begins from around 6–8 weeks of age. For feline panleukopenia, herpesvirus and calicivirus, veterinary guidelines recommend a series of doses through at least 16 weeks of age because maternally derived antibodies can interfere with early vaccination. FeLV vaccination is considered core for kittens and young cats in the AAHA/AAFP framework, while rabies vaccination depends partly on local law and regional risk. Your veterinarian should create the vaccination plan for the individual kitten based on age, health, previous vaccination, lifestyle and location.

New Kitten Checklist: Everything You Need Before Bringing a Kitten Home

Before bringing a kitten home, prepare a quiet safe area with food, fresh water, litter trays, hiding places, comfortable bedding, scratching surfaces and suitable toys. Kitten-proof the home by securing windows, balconies, electrical cables, medicines, chemicals, toxic plants and small objects that could be swallowed. Find a veterinarian in advance, gather the kitten's health, vaccination and identification records, arrange an early veterinary visit and give your kitten time to explore their new home gradually rather than introducing everything at once.

Cat Not Eating? Common Reasons and When to Contact a Vet

A cat may stop eating because of dental pain, nausea, gastrointestinal disease, kidney or liver disease, pancreatitis, infection, pain, stress, medication effects, difficulty accessing food or many other causes. Appetite loss in cats should be taken seriously because prolonged inadequate food intake can contribute to hepatic lipidosis, a potentially life-threatening liver condition, particularly in overweight cats. Contact your veterinarian promptly if your cat stops eating, and seek urgent care sooner if appetite loss occurs with difficulty breathing, collapse, repeated vomiting, severe weakness, suspected poisoning, inability to urinate or other serious symptoms.

Question

How Often Should Your Pet See a Vet?

Most healthy pets benefit from regular preventive veterinary care, but there is no single schedule that is right for every animal. AAHA recommends at least an annual veterinary examination for pets generally, while senior animals and pets with chronic health conditions often need more frequent visits. The right schedule depends on species, age, breed, health, lifestyle and environment.

How to Prepare Your Pet for a Vet Appointment

Prepare for a veterinary appointment by gathering your pet’s relevant medical history, current medications, vaccination information and a short list of questions or symptoms you want to discuss. Plan safe transport in advance and tell the clinic beforehand if your pet is particularly fearful, reactive or difficult to handle. For cats and other carrier-trained pets, making the carrier familiar well before the appointment can help reduce stress. Always follow the veterinary practice’s specific instructions about food, medication or preparation for procedures.

Cat Vomiting: Common Causes and When to Contact a Vet

Cats can vomit for many reasons, ranging from hairballs or a temporary digestive upset to parasites, foreign-body obstruction, toxins, inflammatory gastrointestinal disease, pancreatitis, kidney disease, hyperthyroidism, diabetes or cancer. Vomiting is an active process usually involving nausea, retching and abdominal contractions, while regurgitation is generally more passive. An isolated episode in an otherwise well cat may sometimes be monitored, but repeated or persistent vomiting, blood, appetite loss, weakness, diarrhea, dehydration, pain, weight loss, inability to keep water down or suspected toxin or foreign-object ingestion requires veterinary advice. Severe or protracted vomiting, collapse, breathing difficulty, marked weakness, a painful or distended abdomen, or inability to urinate requires urgent veterinary attention.

Cat Diarrhoea: Common Causes and Warning Signs

Cats can develop diarrhoea for many reasons, including a sudden diet change, stress, food intolerance, parasites, infections, toxins, inflammatory gastrointestinal disease, pancreatic disease, hyperthyroidism, kidney or liver disease and cancer. Mild, short-lived diarrhoea in an otherwise well adult cat may sometimes resolve without becoming serious, but contact a veterinarian if it persists, becomes frequent or severe, contains blood, appears black or tarry, or occurs with vomiting, appetite loss, weakness, abdominal pain, dehydration or weight loss. Kittens, senior cats and cats with existing medical conditions may become unwell more quickly. Severe or persistent diarrhoea, collapse, marked weakness, significant dehydration, breathing difficulty, suspected poisoning or rapid deterioration requires urgent veterinary attention.

Signs Your Cat May Be Sick: When to Contact a Vet

Signs that a cat may be unwell include eating less, drinking or urinating more or less than usual, vomiting, diarrhoea, constipation, weight loss, hiding, lethargy, unusual behaviour, reduced grooming, mobility changes, coughing, rapid or difficult breathing, eye or nose discharge, skin or coat changes and changes in litter-tray habits. Cats can sometimes show illness subtly, so a meaningful change from your cat's normal routine may be important even when no dramatic symptom is present. Contact a veterinarian if a change persists, recurs or occurs with other concerning signs. Seek urgent veterinary care for difficulty or open-mouth breathing, collapse or unresponsiveness, seizures, severe weakness, inability to urinate, major trauma or bleeding, abnormal gum colour, suspected poisoning or rapid deterioration.
