The surroundings are different. Familiar smells may have disappeared. The people are new. Food may be presented differently. Other animals may be nearby. Even everyday sounds—from household appliances to traffic—may be unfamiliar.

For some pets, curiosity takes over quickly. Others need considerably longer before they feel secure.

The objective of the first week is therefore not to make your new pet experience everything your household has to offer.

It is to create a safe foundation from which they can adjust.

International Cat Care, for example, recommends initially giving a new kitten a quiet, safe area from which to explore gradually rather than immediately exposing them to the whole home. Rabbit welfare guidance similarly recommends allowing newly moved rabbits to emerge and interact at their own pace. The details vary by species, but the underlying principle is remarkably consistent: reduce unnecessary pressure and let confidence develop gradually. International Cat Care

Before your pet arrives: prepare the environment

The best first day begins before the pet enters the home.

Decide where they will initially eat, drink, rest, toilet where applicable and retreat when they want to be left alone. Check the environment from the animal's perspective rather than your own.

Electrical cables may need protection. Windows, doors, balconies, gardens, fencing or enclosure openings may create escape risks. Houseplants, medicines, household chemicals and human foods may be toxic. Small objects may be swallowed. Other animals may need to be physically separated initially.

The hazards are species-specific. A rabbit may chew a cable that appears irrelevant to a cat. A bird may reach something by flying that appears inaccessible from the floor. A reptile needs appropriate environmental parameters rather than a generic room-temperature setup.

The question should always be:

What could this species reach, chew, climb, fly into, ingest, escape through or become trapped inside?

Keep the first day quiet

It can be tempting to turn arrival day into a celebration.

Family members want to meet the new pet. Friends want to visit. Children want to hold them. Everyone wants photographs.

For the animal, however, arrival itself may already provide more than enough novelty.

For puppies, Blue Cross advises keeping the early settling period relatively quiet and avoiding too many visitors while the puppy adjusts. International Cat Care similarly recommends a quiet initial environment for kittens. BlueCross

The exact approach differs between species and individuals, but the principle is broadly useful:

Arrival day should prioritise settling over entertainment.

Show the pet their essential resources. Keep interactions calm. Allow rest. Avoid unnecessary handling, particularly in species that may find restraint stressful.

A confident animal may begin exploring quickly.

A cautious one may not.

Neither response means the first day has failed.

Give your pet somewhere safe to retreat

A safe place is not where you put the pet when you want them out of the way.

It is somewhere the animal can choose to use.

For a cat, this might include a quiet introductory room with hiding and elevated options. International Cat Care recommends providing new kittens with quiet hiding areas and initially limiting them to a safe room while they adapt. International Cat Care

For a rabbit, hiding places form part of an appropriate living environment, and guardians should avoid forcing rabbits from their safe areas. Rabbit Welfare Association & Fund (RWAF)

For a guinea pig, bird, hamster or reptile, security will look different again.

This is why a universal:

“new pet safe room”

is not appropriate for every species.

The universal principle is:

YOUR PET NEEDS A SPECIES-APPROPRIATE WAY TO FEEL SECURE AND WITHDRAW FROM INTERACTION.

Children and visitors should understand that retreat means:

leave the pet alone.

Do not force exploration

Some animals will begin investigating immediately.

Others may remain close to a hiding area.

Avoid repeatedly pulling a reluctant animal into the open because you want them to:

“get used to the house.”

For rabbits, welfare guidance specifically recommends letting them enjoy their space rather than forcing them out, which can increase fear. Rabbit Welfare Association & Fund (RWAF)

The same broader principle applies across many species.

Give the animal access to an appropriately sized safe environment and let exploration expand according to their behaviour and species needs.

Confidence is not measured by how much of the home a pet has seen by the end of Day 1.

Keep familiar food consistent initially

Moving home already changes many things.

Unless there is a medical or safety reason to change immediately, avoid simultaneously making an abrupt diet change simply because you prefer another food.

Find out what the animal has been eating and obtain accurate information about:

food type, amount, frequency and any supplements or specialist feeding requirements.

If a transition is appropriate, it can usually be planned gradually according to the species and veterinary advice.

This is particularly important because sudden dietary change can cause digestive problems in some animals, while refusing food can itself be clinically significant in species such as rabbits, guinea pigs and cats.

Do not assume:

“They'll eat when they're hungry.”

If a new pet is not eating as expected, consider the species, age, health status and duration of the change and seek veterinary advice where appropriate.

Learn what normal eating looks like immediately

The first week gives you an opportunity to establish a baseline.

Instead of recording only:

Food provided ✓

notice:

Did they actually eat?

How enthusiastically?

Which foods?

When?

Was this different from what the previous guardian reported?

For rabbits and guinea pigs, interest in hay can be particularly useful information.

For birds, species-specific food intake and body-weight trends can matter.

For reptiles, feeding frequency and normal appetite can vary enormously by species, age, temperature, season and reproductive status.

For dogs and cats, appetite can still be affected by stress, illness or abrupt dietary change.

The first week's objective is not to decide what:

a normal pet

does.

It is to start learning:

what is normal for this pet.

Check drinking and hydration

Make sure fresh water is available in a form appropriate to the species.

If the pet has come from another home, ask how water was previously provided.

Some animals may be accustomed to a particular bowl, bottle or drinking location. For rabbits moving home, RWAF even notes that changes in the taste of local water can sometimes affect acceptance and suggests transitioning water where needed. Rabbit Welfare Association & Fund (RWAF)

You do not need to obsessively measure every sip in a healthy animal.

But you should know whether your pet appears to be drinking and whether that changes substantially.

A marked increase or decrease in drinking can be clinically relevant and belongs in the health record.

Toileting can tell you a great deal

What you monitor depends on the species.

For a cat, observe litter-tray use.

For a dog, begin learning their urination and defecation routine.

For rabbits and guinea pigs, droppings provide important information alongside appetite.

For birds, changes in droppings can contribute to health monitoring.

For reptiles, elimination patterns depend heavily on species, feeding and environmental conditions.

During the first week, you are establishing:

frequency + appearance + location + individual pattern.

Do not punish accidents.

A newly arrived animal may be learning a completely new environment and routine.

For cats, International Cat Care notes that an initial safe room can help maintain successful litter-tray use while a kitten gradually adjusts to the home. International Cat Care

Maintain familiar routines where you can

If you know the pet's previous routine, preserve useful elements initially.

Ask:

When were they fed?

When did they sleep?

When were dogs usually walked?

What substrate or litter did they use?

What cues were they trained to understand?

Did they have a favourite resting place?

Were they used to being covered at night, where appropriate for the species?

Which companion animals did they live with?

Blue Cross recommends maintaining as much normality as possible when dogs adjust to a new home because familiar routines can help them settle. BlueCross

Routine should not become rigid.

But predictability can make an unfamiliar environment easier to understand.

Collect every existing health record

One of the most valuable things you can do during the first week is gather the pet's existing information before documents disappear into drawers, email chains and messaging apps.

Collect whatever exists:

vaccination records, previous veterinary records, microchip or identification information, medication details, parasite-treatment history, allergies or adverse reactions, previous diagnoses, surgical history, insurance documentation where applicable, diet information and relevant laboratory or imaging results.

For dogs, the AVMA specifically recommends taking existing vaccination and deworming information to the first veterinary examination. AVMA

But the principle applies far beyond dogs.

For a horse, records may also include passport or identification documents, farriery, dentistry and competition-related records.

For a bird, reptile or exotic mammal, species, sex where known, provenance, previous husbandry and environmental information can be especially valuable.

Do not wait until an emergency to discover that the medical history is still with the previous guardian.

Verify identity information

Check whatever identification applies to the animal and jurisdiction.

This might include:

microchip, tag, registration, passport, band, ring, tattoo or another formal identifier.

Confirm that the details are correct and that the appropriate registration database or authority has the current guardian's information where applicable.

Identification laws vary substantially by country and species, so 1KAHU should never tell every guardian globally:

“You must register your pet's microchip within X days.”

Instead, the platform should know:

PET + SPECIES + LOCATION + IDENTIFICATION TYPE

and direct the guardian to the relevant local requirement.

Digital records can organise identification information.

They do not replace legally required original documents or official registries.

Arrange appropriate veterinary care

A new pet should be connected with an appropriate veterinary professional rather than waiting until something goes wrong.

For dogs, the AVMA recommends scheduling a veterinary examination as soon as possible and bringing the animal's previous medical information. AVMA

The appropriate timing for other species depends on age, source, health, previous care and circumstances.

The more important rule is:

FIND THE RIGHT VETERINARIAN BEFORE YOU NEED THEM URGENTLY.

For a dog or cat, this may be straightforward.

For rabbits, birds, reptiles, guinea pigs, hamsters and other less commonly treated species, verify that the clinic genuinely sees that species.

Article 28 established this principle for exotic pets:

Find species-appropriate veterinary expertise before the emergency.

For horses, establish both routine veterinary care and how emergency/out-of-hours care is handled.

The first veterinary visit is more than vaccinations

A first appointment can establish much more than a vaccination schedule.

Depending on the species and individual, your veterinarian may review:

body condition, weight, diet, previous records, parasite risk, dental health, reproductive status, preventive care, behaviour, identification and environmental management.

The visit also gives the guardian an opportunity to clarify which preventive-care recommendations actually apply in their region.

Vaccination recommendations differ between species and jurisdictions.

Parasite risks vary geographically.

Neutering decisions and timing depend on species, sex, age, health and individual circumstances.

This is why 1KAHU should not generate one universal:

New Pet Medical Checklist

with identical interventions for every animal.

Know where you would go in an emergency

Do not wait for midnight on a public holiday to search:

“emergency vet near me.”

During the first week, establish:

your regular veterinary clinic,

the out-of-hours arrangement,

the nearest appropriate emergency provider,

how you would transport the pet,

and any specialist facility you may need.

For horses and some exotic species, emergency planning can be particularly important because the nearest suitable provider may not be the nearest veterinary clinic.

Keep essential contact information accessible to everyone responsible for the animal.

Article 7's emergency-information framework should be linked directly from the first-week onboarding journey.

Introduce family members gradually

A new pet does not need to meet everyone immediately.

Let interactions happen at a pace appropriate to the animal.

For a new dog, Blue Cross recommends supervision and allowing the dog to approach children rather than children crowding around the dog. BlueCross

The underlying principle is valuable more broadly:

LET THE PET HAVE SOME CONTROL OVER PROXIMITY.

Children should learn that sleeping areas, hides, cages, enclosures and resting locations are not places to reach in and retrieve an animal for interaction.

Supervision is particularly important around young children, regardless of how:

friendly

the new pet is believed to be.

Animals and children are both unpredictable in unfamiliar situations.

Existing pets need careful introductions

Do not assume two animals will:

“work it out.”

Introductions should reflect species, individual temperament, health, predatory relationships and previous social experience.

A dog and cat may initially need physical separation and controlled scent-based introduction. Blue Cross recommends keeping newly introduced cats and dogs separate initially and using scent exchange before closer interaction. BlueCross

A new rabbit should not simply be placed with an unfamiliar rabbit.

A guinea pig should not simply be dropped into an established group.

Bird introductions require consideration of species, health and compatibility.

Predator-prey combinations require particularly careful management. RWAF specifically cautions that indoor rabbits should be protected from cats and dogs even when those animals appear friendly. Rabbit Welfare Association & Fund (RWAF)

The first week is not a deadline for friendship.

Consider health before animal-to-animal contact

If the new pet's health status is unknown, veterinary assessment may be appropriate before close contact with resident animals.

Depending on species and circumstances, infectious disease, parasites or other health concerns may affect how introductions should be managed.

This is particularly relevant in multi-animal homes, breeding environments, aviaries, stables and households with vulnerable animals.

There is no single universal quarantine period appropriate to every species and situation.

Ask the relevant veterinarian what precautions are appropriate.

Do not mistake overwhelm for “socialisation”

New guardians often want to expose a pet to:

people,

traffic,

children,

other animals,

vehicles,

grooming,

new places,

and dozens of experiences

as quickly as possible.

For puppies in particular, early socialisation is developmentally important. But good socialisation is not simply maximum exposure.

It means creating safe, appropriately controlled experiences rather than flooding the animal with stimuli.

For an adult rescue, frightened cat, rabbit, bird or other species, the behavioural priorities can be very different.

The first week should therefore avoid a universal:

“meet 10 new people”

checklist.

Observe the individual in front of you.

Start learning behaviour before trying to change it

A newly arrived pet may behave differently from how they will behave once settled.

A dog may be unusually quiet.

A cat may hide.

A rabbit may explore less.

A bird may interact cautiously.

A guinea pig may spend more time under cover.

These observations matter, but avoid deciding after 48 hours:

“This is their personality.”

Record what you see.

Note context.

Allow adjustment.

At the same time, do not dismiss significant health-related changes as:

“They're just settling in.”

The challenge is distinguishing normal adjustment from a possible medical problem.

That is where appetite, elimination, weight, posture, breathing and other health indicators become important.

Start an individual baseline

By the end of the first week, you should know more about your pet than you did on Day 1.

Not just:

Breed: Labrador Retriever

but:

eats breakfast immediately drinks after walks prefers sleeping near the kitchen cautious around traffic settles after visitors leave highly motivated by food

Or for a rabbit:

hay interest high droppings normal active early morning/evening prefers covered hide approaches voluntarily after several minutes

Or a bird:

morning vocalisation normal weight stable favourite perch identified foraging high cautious with unfamiliar objects

This becomes the beginning of:

MY PET'S NORMAL.

That baseline can become clinically useful later.

Do not introduce every new product in Week 1

A new home often comes with:

a new food,

new bed,

new treats,

new litter,

new toys,

new harness,

new supplements,

new grooming products,

and a new routine.

Changing everything at once makes it harder to understand what the animal responds well—or badly—to.

Keep essential familiar items where practical.

Introduce non-essential changes gradually.

This is particularly important for species that may respond strongly to dietary or environmental change.

The goal of Week 1 is:

STABILITY FIRST. OPTIMISATION SECOND.

Start training with useful everyday behaviours

For species capable of appropriate cooperative training, the first week can begin to establish simple positive associations.

For a dog, that may include responding to their name, toileting routines, settling and comfortable handling.

For a cat, it might involve carrier familiarity or approaching voluntarily.

A rabbit or guinea pig may begin learning to approach a familiar cue or enter a carrier.

A bird can begin building positive associations with a station, carrier or weighing perch.

A horse may need to learn new stable, turnout or handling routines.

Training should not be about proving:

“My new pet is obedient.”

It should help make everyday care:

predictable + cooperative + safe.

Set up preventive reminders—but only after verifying the schedule

Once you have existing records and veterinary guidance, create reminders for relevant care.

These may include:

vaccinations,

parasite management,

medications,

veterinary reviews,

dental care,

weight checks,

grooming,

farriery,

or other species-specific care.

Do not blindly import a generic schedule from the internet.

Vaccination and parasite recommendations depend on species, age, health, lifestyle and geography.

The professional due date should remain the authoritative source where one has been provided.

Record medications accurately

If the pet arrives taking medication, record:

exact product, strength, dose, route, frequency, reason, prescribing veterinarian and instructions.

Do not rely on:

“the little white tablet twice a day.”

Keep the original label and packaging.

If instructions are unclear, contact the prescribing clinic rather than guessing.

Do not stop, double or alter prescribed medication simply because the pet appears better or because moving home disrupted the schedule.

Consider insurance or financial planning early

Veterinary emergencies can occur shortly after adoption or purchase.

Where pet insurance is available and appropriate, investigate coverage early and understand:

waiting periods,

exclusions,

pre-existing-condition definitions,

deductibles or excess,

annual or lifetime limits,

and geographic coverage.

Insurance markets and regulation differ substantially worldwide, so this is another area where the Academy should avoid recommending one universal product structure.

If insurance is not available or suitable, consider another realistic emergency-care financial plan.

The important question is:

If my pet needs unexpected veterinary care tomorrow, how will I manage it?

Day-by-day: the first week

The exact sequence should remain flexible, but a practical first week can look like this:

Day 1 — Safety and decompression

Bring your pet into the prepared environment. Show them essential resources and allow them to investigate at their own pace.

Keep visitors and unnecessary handling to a minimum.

Confirm that they can access food, water, resting or hiding areas and appropriate toileting facilities.

Observe rather than overwhelm.

Day 2 — Establish the basic routine

Begin creating predictable patterns around feeding, cleaning, exercise or movement, rest and interaction.

Check appetite, drinking and elimination.

Continue using familiar food and husbandry where appropriate.

Start collecting previous records.

Day 3 — Learn the individual

Notice where the pet chooses to rest.

What makes them approach?

What makes them retreat?

When are they most active?

How do they respond to normal household activity?

Do not rush to label behaviours. Start building the baseline.

Day 4 — Health and records

Confirm your veterinary arrangements.

Upload or organise previous medical information.

Verify identification details.

Record medication, allergies, existing diagnoses and preventive-care history.

Establish emergency contacts.

Day 5 — Expand gradually

If the animal is settling comfortably and the species makes it appropriate, allow controlled expansion into more of the environment or introduce another low-pressure experience.

Do not expand simply because:

“It's Day 5.”

The pet's behaviour determines the pace.

Day 6 — Review relationships and environment

If there are other pets, review how controlled introductions are progressing.

Check whether resources are accessible without competition.

Look for hazards you missed before arrival.

Ask whether the environment actually suits the way this individual animal uses it.

Day 7 — Build the ongoing care plan

Review what you have learned.

You should now have the beginnings of:

HEALTH BASELINE + ROUTINE + BEHAVIOUR BASELINE + CARE TEAM + RECORDS + EMERGENCY PLAN.

The first week ends.

Learning your pet does not.

Your First-Week Checklist

By the end of the first week, aim to have covered the following where relevant to the species and individual:

• Safe environment: pet-proofed, escape risks addressed and appropriate hiding/resting areas available.
• Food and water: familiar diet confirmed, normal appetite beginning to be understood and fresh water reliably accessible.
• Elimination: normal urination, faeces, droppings or litter habits being monitored as appropriate.
• Veterinary care: appropriate veterinary provider identified and first examination arranged where needed.
• Medical records: previous records, vaccination history, medications and known health conditions collected.
• Identification: microchip, tag, passport, ring or other relevant identification checked and details updated where required.
• Emergency plan: emergency provider, transport plan and essential contact information available.
• Introductions: people and other animals introduced gradually rather than forced.
• Routine: feeding, rest, exercise/movement, cleaning and care beginning to follow a predictable pattern.
• Baseline: first observations of normal appetite, activity, behaviour, social interaction and other species-relevant indicators recorded.

This is a checklist for establishing care—not a test the pet must complete within seven days.

When to Contact a Veterinarian

Do not assume every change is simply part of:

“settling in.”

Seek veterinary advice if your new pet develops concerning signs such as difficulty breathing, collapse, seizures, significant bleeding, suspected toxin exposure, severe injury, repeated vomiting where relevant, inability to urinate, marked weakness, significant pain or another acute deterioration.

Other changes may require prompt assessment depending on species and severity, including refusing food, substantial reduction in appetite, abnormal droppings or elimination, persistent diarrhoea, unusual inactivity, abnormal posture, weight loss, discharge or sudden behavioural change.

Species matters enormously.

A rabbit or guinea pig with reduced food intake and droppings may require prompt assessment.

A male cat repeatedly attempting to urinate without producing urine can have a life-threatening obstruction.

A bird that suddenly becomes unusually quiet or stops eating may be seriously unwell despite subtle outward signs.

A reptile's normal feeding interval may differ dramatically from a mammal's, so the same observation can have a different meaning.

When uncertain, contact a veterinarian who treats that species.

Frequently Asked Questions

How long does it take a new pet to settle into a home?

There is no universal timetable. Species, age, temperament, previous experiences, health and environment all influence adjustment. Some animals explore almost immediately; others may need days or considerably longer before behaving confidently. Judge progress against the individual rather than a fixed “three-day” or “three-week” rule.

Should I take my new pet to the vet during the first week?

It is sensible to establish veterinary care promptly, but the exact timing depends on species, age, source, previous veterinary history and current health. The AVMA recommends an examination as soon as possible for a newly acquired dog. AVMA For other species, arrange an appropriate examination according to the animal's circumstances and seek care sooner if there are health concerns.

Should I let my new pet explore the whole house immediately?

Not necessarily. Some pets benefit from initially having a smaller, secure environment and expanding access as confidence develops. International Cat Care recommends a quiet introductory room for new kittens, while rabbit guidance similarly supports giving newly moved rabbits time and space to adjust. International Cat Care The right approach depends on species and individual behaviour.

Should I change my new pet's food immediately?

Usually avoid unnecessary abrupt changes if the existing food is safe and appropriate. Obtain details of the previous diet and make any planned transition according to species-specific nutritional guidance. If the existing diet is medically inappropriate or unsafe, ask your veterinarian how to change it.

How should I introduce my new pet to animals already at home?

Gradually and according to the species involved. Do not rely on unsupervised “let them work it out” introductions. Cats and dogs, for example, may benefit from initial separation and scent exchange before controlled meetings. BlueCross Rabbit, guinea pig, bird and other social introductions require their own species-specific approaches.

Is hiding normal for a new pet?

It can be. A new environment contains unfamiliar sights, sounds and smells, and retreat can help some animals feel secure. International Cat Care specifically recommends hiding opportunities for newly arrived kittens. International Cat Care However, hiding accompanied by reduced appetite, pain, breathing changes, abnormal elimination or another significant health change should not automatically be dismissed as adjustment.

What information should I collect when I get a new pet?

Collect identification details, previous veterinary records, vaccination history where applicable, medications, known diagnoses, allergies or adverse reactions, diet information and relevant preventive-care history. Depending on species, also gather documents such as passports, provenance records, laboratory results, husbandry information or previous specialist-care records.

1KAHU: The First Week Should Build the Pet's Care Foundation

For 1KAHU, Article 68 should connect directly to onboarding.

When a guardian creates a new pet, the platform can guide them through a short First Week Setup covering identity, existing medical records, medications, veterinary provider, emergency contact, diet and the first observations of the pet's normal routine.

The experience should remain species-aware. A rabbit guardian may be prompted to observe hay intake and droppings; a bird guardian may establish weight, food intake and normal vocal/activity patterns; a horse guardian may add veterinarian, farrier, dentist, forage, turnout and emergency arrangements.

Crucially, 1KAHU should not create a:

“Your pet is 72% settled”

score.

Adjustment cannot be reduced credibly to a percentage.

Instead, the first week creates the beginning of the longitudinal pet profile:

IDENTITY → RECORDS → CARE TEAM → ROUTINE → BASELINE → REMINDERS

That information can later help AI Guardian recognise meaningful change, while diagnosis and treatment remain with qualified veterinary professionals.
