Many behaviours guardians find unusual—including scratching, kneading, scent rubbing, hiding, climbing and hunting-like play—are normal parts of feline behaviour. What often matters most is change. If your cat suddenly starts hiding, vocalising, avoiding touch, toileting differently or interacting differently, consider health, pain, fear and environmental stress rather than assuming they are being difficult.

The central principle is:

Do not ask only, “What does this behaviour mean?” Ask, “What does it mean for this cat, in this context, compared with their normal behaviour?”

Cats are communicating all the time

Cats do not communicate through one simple dictionary of gestures.

They use combinations of body position, tail movement, ears, eyes, facial tension, vocalisation, scent marking, proximity and movement. Their environment and previous experiences influence those signals too.

This is why simplified rules such as:

purring = happy

or:

tail moving = angry

can be misleading.

The same behaviour may appear in different emotional states, and several signals considered together are usually more informative than one body part.

Modern veterinary welfare guidance emphasises understanding species-specific body language and behavioural expression as part of good companion-animal care.

For 1KAHU, this creates an important rule:

BEHAVIOUR + CONTEXT + INDIVIDUAL BASELINE + CHANGE OVER TIME

is more meaningful than:

BEHAVIOUR = FIXED MEANING.

Scratching is normal feline behaviour

A cat scratching the sofa is not necessarily being destructive in the behavioural sense.

Scratching has several functions. It helps maintain the claws, provides physical stretching and leaves visual and scent-related information in the environment. The behaviour itself is normal; the disagreement is usually about location.

That distinction matters.

Punishing the cat for scratching does not remove the underlying behavioural motivation. A more useful strategy is to provide attractive scratching opportunities in relevant locations and understand the cat's preferences.

Some cats favour vertical surfaces. Others frequently use horizontal or angled ones. Texture, stability and placement can all affect whether a scratching surface is actually used.

Instead of:

How do I stop my cat scratching?

the better question is:

Where and how does my cat prefer to scratch, and how can I provide an acceptable outlet there?

This follows the broader welfare principle of allowing animals appropriate opportunities to perform species-specific behaviour.

Why do cats knead?

Kneading describes the rhythmic alternating movement of the front paws that cats sometimes make against blankets, beds, people or other soft surfaces.

It begins very early in life: kittens knead around the mother's mammary area while nursing. Some cats retain the behaviour into adulthood and may knead while relaxed or settling.

But kneading should not be turned into an overly specific emotional translation.

A cat kneading does not necessarily mean:

“I think you are my mother.”

Nor can kneading alone prove that a cat is completely relaxed.

Look at the rest of the interaction. A cat voluntarily settling on a soft blanket, with relaxed posture and other comfortable behaviour, provides much more context than the paw movement alone.

The useful principle is:

Interpret the whole cat—not one gesture.

Why do cats rub against people and objects?

Cats have scent glands in several areas of the face and body. Facial or body rubbing can deposit scent while also forming part of social interaction and environmental communication.

A cat may rub against:

a familiar person, furniture, doorframes or other objects in their environment.

When a cat approaches with relaxed body language and rubs against you, it can be part of a friendly social interaction.

But rubbing does not necessarily mean:

“Please stroke me everywhere.”

The cat may want proximity without prolonged handling.

Observe what happens next.

Does the cat remain?

Lean toward contact?

Move away?

Turn their body?

Become tense?

The interaction is a conversation, not blanket consent for continued touching.

A raised tail can be socially meaningful

When a relaxed cat approaches a familiar person or compatible cat with the tail held upright, this can form part of friendly social communication.

But again, posture should not be reduced to an emoji-style translation.

Look at:

tail position + body tension + ears + movement + distance + environment.

A cat approaching smoothly with an upright tail and relaxed body presents a very different picture from one with an enlarged tail, arched posture and clear signs of arousal.

The tail contributes information.

It does not tell the entire story.

Tail movement does not have one universal meaning

A rapidly moving dog's tail is often interpreted—sometimes incorrectly—as automatically friendly.

With cats, guardians can make a similar mistake in the opposite direction and interpret any tail movement as:

anger.

Tail movements vary in speed, amplitude and context.

A cat may move the tip of the tail while intensely watching something.

A larger, faster movement during handling may appear as arousal or increasing intolerance.

A puffed tail can accompany high arousal, including fear.

The important skill is not memorising:

tail movement X = emotion Y.

It is recognising clusters of signals and changes in intensity.

Ears provide useful context

A relaxed cat may hold the ears in a relatively neutral forward or outward position.

As attention changes, the ears may orient toward sounds independently.

Flattened or rotated ears can occur with fear, defensive behaviour, discomfort or high arousal depending on context.

Again, avoid diagnosing emotional state from ears alone.

If a cat's ears move back while:

pupils change, body becomes tense, tail begins moving strongly, and the cat turns away during petting,

the combined sequence is more informative than:

ears back.

Learning to notice sequences can help guardians end an interaction before the cat feels the need to escalate further.

Eyes matter—but pupil size is not an emotion detector

Cats' pupils change with light.

They can also change with arousal.

That means very large pupils can occur in multiple contexts, including:

low light, play, excitement, fear or stress.

Small pupils likewise cannot be translated into one emotional state without considering lighting and the rest of the body.

A better approach is to ask:

What changed?

If the room lighting is stable but the cat's pupils enlarge as their posture lowers and ears rotate during an unfamiliar event, the combination becomes more meaningful.

This is another reason AI should never interpret feline emotion from one visual feature alone.

Why do cats purr?

Purring is strongly associated with comfortable feline interactions, and many cats purr while resting, receiving contact or nursing.

But:

purring does not guarantee that a cat is happy.

Cats can also purr in other contexts, including when frightened, unwell, injured or receiving veterinary care.

A cat that is:

purring + relaxed + voluntarily interacting + eating normally

presents a very different picture from:

purring + hunched + withdrawn + not eating.

Treat purring as one piece of information, not a diagnostic signal.

If other behaviour suggests pain or illness, purring should never reassure a guardian into ignoring those signs.

Meowing is heavily influenced by the human-cat relationship

Adult cats use vocal communication in several contexts, and meowing is particularly prominent in cat-human interaction.

A cat may vocalise because they have learned that it produces:

attention, food, access or another response.

Different cats also simply vocalise more than others.

This is why:

“My cat meows a lot.”

is difficult to interpret without a baseline.

The more useful question is:

“Is this normal for my cat?”

A naturally vocal cat who has always greeted the guardian loudly is different from a previously quiet cat who suddenly begins vocalising repeatedly at night.

The second situation deserves more investigation.

A change in vocalisation can be medically important

New or increased vocalisation can occur alongside:

pain, sensory decline, cognitive changes, endocrine disease, urinary problems, gastrointestinal discomfort, reproductive behaviour or stress, among other possibilities.

This becomes particularly relevant in older cats.

If vocalisation changes substantially—especially when accompanied by altered sleep, appetite, drinking, toileting, mobility or orientation—speak with your veterinarian.

The behaviour is not the diagnosis.

It is information.

Why do cats hide?

Hiding is a normal feline strategy.

Cats may seek enclosed or secluded locations to:

rest, feel secure, avoid disturbance or regulate interaction.

WSAVA's global welfare guidance specifically recognises the value of perching and hiding opportunities for cats.

A healthy cat choosing their favourite box for an afternoon sleep is therefore not inherently concerning.

What matters is the pattern.

If Luna normally:

sleeps on the sofa, greets the household, plays every evening,

and suddenly spends almost the entire day under the bed, the change is more significant.

Hiding can increase with:

fear, social stress, pain or illness.

The correct question is not:

“Is hiding normal?”

It is:

“Is this amount and context of hiding normal for this cat?”

Why do cats suddenly run around the house?

Short bursts of high-energy running—often called “zoomies”—can occur during normal play and activity.

Young cats may show them particularly often.

Some cats have predictable active periods associated with their daily rhythm, play or toileting.

In an otherwise healthy cat, occasional bursts of running are usually not a problem.

But a sudden dramatic change in activity should still be interpreted in context.

If frantic movement appears alongside:

skin twitching, persistent licking, distress, vocalisation, disorientation or another new sign, the situation deserves closer attention.

As throughout this article:

NORMAL BEHAVIOUR + SUDDEN CHANGE = REASSESS.

Hunting behaviour does not mean your cat is hungry

Cats can perform hunting and predatory behaviours even when adequately fed.

Stalking.

Chasing.

Pouncing.

Grabbing.

Biting.

These behaviours form part of the feline repertoire rather than simply representing an attempt to obtain enough calories.

This is why interactive play remains relevant for an indoor cat with a nutritionally complete diet.

Article 61 explored how appropriate play can provide opportunities for these behaviours.

It also explains why:

feeding more

is not necessarily the answer to:

a cat wanting to stalk and chase.

Nutrition and predatory motivation overlap, but they are not identical.

Bringing prey or toys to the guardian does not need a human story

A cat may carry prey, toys or other objects through the home.

It is tempting to explain this as:

“She's bringing me a gift.”

or:

“She's trying to teach me to hunt.”

Those stories may be appealing, but we should be cautious about assigning complex human-style motives when the observable behaviour can be understood within feline predatory and object-carrying behaviour.

The stronger Academy approach is:

describe what we know before inventing what the cat is thinking.

This principle should apply across all behaviour content.

Why do cats knock objects off surfaces?

There is no single explanation.

A cat may investigate an object with the paw, discover that moving it is interesting, seek interaction, or incorporate the object into exploratory or play behaviour.

If knocking an object reliably makes the guardian immediately run over, the consequences can also help maintain the behaviour.

The practical response depends on the situation.

Protect dangerous or valuable objects.

Provide appropriate opportunities for exploration and play.

And avoid assuming:

“My cat is doing it to annoy me.”

Human annoyance is not necessary to explain the behaviour.

Why do cats sleep so much?

Cats normally spend substantial portions of the day resting and sleeping.

The amount varies with:

age, health, activity, environment and individual routine.

A kitten's pattern will differ from that of an adult or senior cat.

What matters clinically is often not:

“Cats sleep a lot.”

but:

“My cat is sleeping substantially more than usual and no longer joins activities they normally enjoy.”

Changes in rest patterns can be useful health information, especially when they appear alongside reduced appetite, hiding, mobility changes or altered social behaviour.

Baseline matters again.

Why do cats follow people around?

Sometimes the explanation is uncomplicated:

the cat wants access, attention, food, play, proximity or information about what is happening.

Some cats are highly socially engaged with their guardians.

Others prefer more independent interaction.

Following is not automatically evidence of:

separation anxiety

or:

overdependence.

Consider when it occurs and what happens next.

Does the cat follow only near mealtimes?

When a particular person returns home?

Before play?

Everywhere?

Has the behaviour changed suddenly?

Context converts a generic behaviour into useful information.

Belly exposure does not automatically mean “rub my stomach”

A cat lying on their back may be relaxed and comfortable.

But exposing the abdomen is not universal permission for abdominal handling.

Some cats enjoy it.

Many do not.

If the cat grabs, kicks or bites when the guardian reaches toward the abdomen, that does not necessarily mean they:

“tricked”

the person.

The guardian may simply have interpreted a relaxed posture as an invitation for a specific type of touch.

Again:

BODY POSITION ≠ AUTOMATIC CONSENT.

Learn how the individual cat prefers to be touched.

Why do cats lick themselves?

Grooming is normal and important.

Cats groom to maintain the coat and may also groom in social or behavioural contexts.

But substantial changes deserve attention.

Excessive grooming or hair loss may be associated with:

itch, parasites, dermatological disease, pain or behavioural stress, among other causes.

Reduced grooming can also be meaningful.

A cat experiencing pain, illness, obesity or reduced mobility may struggle to maintain the coat normally.

So:

MORE GROOMING

and:

LESS GROOMING

can both become relevant when they represent a change from baseline.

Do not diagnose:

“stress grooming”

without considering medical causes.

Why does my cat bite during petting?

A cat may initially seek contact and later reach a point where they no longer want it.

Guardians sometimes describe the subsequent bite as:

“completely out of nowhere.”

But there may have been earlier signals:

body tension, tail movement, skin movement, ear position, turning toward the hand or attempts to leave.

Learning these individual signals can allow interaction to stop before escalation.

This does not mean every bite is caused by overstimulation.

Fear, pain, play and other contexts can also produce biting.

A cat that suddenly becomes sensitive to touch in an area that was previously comfortable should be assessed for pain or illness rather than treated as a behavioural problem alone.

Cats do not act “guilty” or “spiteful” in the human sense

A cat urinates on the bed after the guardian returns from holiday.

The story becomes:

“She is punishing me.”

A cat scratches the new sofa.

“He knows he's not allowed.”

A cat pushes an object off a table.

“She's doing it for revenge.”

These interpretations may feel intuitive because humans naturally assign motives to behaviour.

But they can lead to poor decisions.

The 2014 AAFP/ISFM house-soiling guidelines explicitly emphasise that house-soiling should not be framed as spite or anger toward the caregiver. Medical, environmental and social factors need to be investigated instead.

The more useful framework is:

WHAT HAPPENED? → WHAT WAS THE CONTEXT? → WHAT NEED OR MOTIVATION MAY BE INVOLVED? → HAS HEALTH BEEN CONSIDERED?

not:

“My cat knows better.”

House-soiling is information, not misconduct

A cat urinating or defecating outside the litter tray deserves careful attention.

Possible contributors include:

urinary or gastrointestinal disease, pain, litter preference, tray design, location, cleanliness, access, environmental stress, social tension and marking behaviour.

This is why feline veterinary guidance uses the neutral term house-soiling rather than language that implies wrongdoing. The AAFP/ISFM guidelines recommend both veterinary investigation and optimisation of the litter environment.

Never punish a cat for house-soiling.

Punishment does not identify or resolve the cause and can add stress to an already problematic situation.

A new toileting change belongs in the health record.

Straining to urinate can be an emergency

Behavioural interpretation must stop when an urgent medical problem becomes possible.

A cat repeatedly entering the litter tray, straining, vocalising, producing little or no urine or appearing increasingly distressed may have a urinary problem.

Inability to pass urine—particularly in male cats—can represent a life-threatening obstruction requiring urgent veterinary treatment.

Do not assume:

“He's stressed.”

Do not wait to see whether:

“the behaviour settles.”

This is one of the hard-stop principles already established in Article 36:

REPEATED STRAINING + LITTLE/NO URINE → URGENT VETERINARY ASSESSMENT.

Multi-cat tension can be surprisingly subtle

Cats living together do not need to fight dramatically for tension to exist.

The 2024 AAFP Intercat Tension Guidelines emphasise that tension between household cats is common and often overlooked precisely because signs may be subtle.

One cat may block another's access to a doorway.

A cat may wait until another leaves before approaching food.

One may stare persistently at another.

A cat may stop using a favourite resting location.

Another may spend more time hiding.

Physical fighting can occur, but it is not required.

This means:

“They never fight.”

does not necessarily prove:

“They have a good relationship.”

Observe how cats use space and resources.

Cats sharing a home are not automatically friends

Two cats sleeping in the same house may be:

closely affiliated, tolerant of one another, avoiding one another or experiencing tension.

Relationships can also change.

The arrival of another cat, illness, maturation, environmental changes or resource competition may alter interactions.

The 2024 AAFP guidelines adapt the established feline environmental-needs framework specifically to prevent and manage intercat tension, including attention to resources and social dynamics.

This is another reason Article 61 recommended:

multiple, appropriately separated resources

rather than simply:

more toys.

The environment can influence social behaviour.

Sudden aggression deserves investigation

Aggression is not a personality diagnosis.

It is behaviour occurring in a context.

Fear.

Pain.

Social conflict.

Defensive behaviour.

Predatory behaviour.

Frustration.

Handling.

Resource-related situations.

Different motivations can produce superficially similar outcomes.

If a previously tolerant cat suddenly begins biting when touched, pain should be considered.

If two cats who previously lived comfortably begin fighting, look for environmental and health changes as well as social factors.

Do not simply label the cat:

“aggressive.”

And do not punish aggressive behaviour.

Physical punishment can increase fear and may increase risk to both cat and guardian.

Behaviour can change with age

A kitten's behavioural priorities are not identical to those of a twelve-year-old cat.

Play style can change.

Activity can change.

Sleep can change.

Social preferences may change.

But age should not become an explanation for every behavioural difference.

A senior cat that stops jumping may be experiencing pain.

A cat vocalising unusually at night may have a medical or cognitive problem.

A cat becoming less tolerant of touch may be uncomfortable.

WSAVA's pain guidance emphasises the importance of recognising behavioural changes as part of pain assessment rather than assuming animals will always show obvious physical signs.

Aging changes behaviour.

Disease changes behaviour too.

The two need to be distinguished.

The most important behaviour to understand is your cat's normal

Generic feline knowledge is useful.

Individual knowledge is more powerful.

Imagine Luna's normal pattern is:

greets guardian at the door, eats immediately, plays after dinner, sleeps on top shelf, uses both scratching locations, seeks brief evening contact.

That becomes:

LUNA'S BASELINE.

Now imagine:

greeting stops, appetite falls, play disappears, top shelf is no longer used, hiding increases.

No individual behaviour proves what is wrong.

But the pattern of change is meaningful.

This is where behavioural understanding becomes preventive health care.

Key Facts

• Cat behaviour should be interpreted using the whole body, context and the individual cat's normal pattern, rather than a single gesture.
• Scratching, hiding, climbing, hunting-like play, grooming and scent rubbing are all part of normal feline behavioural repertoires.
• Purring does not automatically mean a cat is comfortable, and hiding does not automatically mean something is wrong. Context matters.
• Behavioural changes can sometimes be among the first signs of pain, illness or environmental stress. Global veterinary guidance recognises behavioural welfare alongside physical health.
• House-soiling should not be interpreted as revenge or spite. Medical, environmental and social causes need to be considered.
• Intercat tension can be subtle and easily missed, even when household cats do not physically fight.
• Sudden aggression or sensitivity to touch can have a pain or medical component.
• A cat repeatedly straining while producing little or no urine requires urgent veterinary attention.
• The most useful question is often not “Is this normal cat behaviour?” but “Is this normal for my cat?”

When to Contact a Veterinarian

Behaviour and health should never be treated as completely separate systems.

Contact your veterinarian when your cat develops a new, persistent or substantial change in behaviour, particularly when several changes occur together. Examples include increased hiding, reduced play, reluctance to jump, new aggression or touch sensitivity, major vocalisation changes, altered grooming, appetite changes, unusual thirst, house-soiling, changes in sleep or unexplained weight change.

Pain deserves particular consideration because cats may show behavioural rather than dramatic physical signs.

Seek urgent veterinary attention if your cat is repeatedly attempting to urinate but producing little or no urine, particularly if they are distressed, vocalising, vomiting, becoming weak or repeatedly visiting the litter tray.

Where physical causes have been assessed but significant fear, aggression, house-soiling or intercat tension persists, your veterinarian may recommend an appropriately qualified feline behaviour professional.

Frequently Asked Questions

Why does my cat knead me?

Kneading originates during kittenhood and can persist into adulthood. Many cats knead soft surfaces or people while settling or during comfortable social situations. Avoid assigning one exact meaning to it; interpret kneading alongside the cat's overall posture and context.

Why does my cat purr and then bite me?

Purring does not mean a cat wants unlimited physical contact. During petting, some cats reach a point where they want interaction to stop. Watch for changes in body tension, tail movement, ears or attempts to move away. If sensitivity to touch is new or occurs around a particular body area, consider veterinary assessment for pain.

Why does my cat hide?

Hiding can be a normal way to rest or feel secure, and access to hiding places is an important part of a cat-friendly environment. A sudden or major increase in hiding, however, can occur with fear, stress, pain or illness and should be considered alongside other changes.

Why does my cat scratch furniture?

Scratching is normal feline behaviour rather than deliberate destruction. Cats may differ in preferred surface, orientation and location. Providing stable, attractive scratching options where the cat naturally wants to scratch is usually more useful than trying to suppress scratching altogether.

Why does my cat follow me everywhere?

Cats may follow people for attention, food, play, access or social proximity, and individual sociability varies considerably. The behaviour becomes more informative when it changes substantially from your cat's normal pattern or occurs alongside other behavioural or health changes.

Are my cats playing or fighting?

Look at the entire interaction rather than one moment. Balanced, reciprocal interactions with opportunities to pause or disengage differ from persistent chasing, blocking, avoidance or one cat repeatedly attempting to escape. Household tension can also exist without obvious fighting, so changes in resource use and avoidance matter.

Why has my cat's behaviour suddenly changed?

Behaviour can change because of environmental events, social relationships, learning, fear or stress, but pain and illness must also be considered. If a change is sudden, persistent or accompanied by appetite, toileting, mobility, grooming, sleep or weight changes, contact your veterinarian.
