Why Do Cats Purr, Knead, Hide, or Meow? Cat Behaviour Explained

Cats have a reputation for being enigmatic, but most of their behaviour is entirely logical once you understand what drives it. Here is a plain-language guide to the most common cat behaviours owners ask about.

Purring

Purring is most often a sign of contentment — but not always. Cats also purr when anxious, in pain, or unwell. Researchers believe purring may have a self-soothing function.

Contentment purring: Relaxed body, half-closed eyes, settled posture. Stress purring: Often accompanied by a tense body, dilated pupils, flattened ears, or unusual context (e.g., at the vet).

If your cat is purring but also hiding, not eating, or seems lethargic, the purr is not a sign that everything is fine.

Kneading

Kneading — pushing paws rhythmically against a soft surface — is a behaviour rooted in kittenhood, when kittens knead their mother to stimulate milk flow. Adult cats do it when content, comfortable, and feeling safe.

It is a compliment. If your cat kneads you, it means they are very relaxed in your presence.

Some cats extend claws during kneading, which can be uncomfortable. Trim nails regularly and provide a blanket for them to knead instead if needed.

Hiding

Hiding is normal behaviour for cats — they are both predators and prey animals, and having access to enclosed, elevated, or hidden spaces makes them feel safe.

Normal hiding: A cat who hides occasionally, especially in new or loud environments, is just decompressing.

Concerning hiding: A cat who suddenly starts hiding more than usual, is not eating, and is reluctant to come out may be unwell. Pain and illness often cause cats to withdraw. If this persists beyond 24 hours, contact your vet.

Excessive Meowing

Cats evolved to meow primarily as communication with humans — adult cats rarely meow at each other. Increased vocalisation can mean:

Hunger — especially if it occurs around feeding times
Attention — if the cat has learned that meowing produces a response
Discomfort or pain — particularly sudden or unusual vocalisations
Cognitive changes — older cats with cognitive dysfunction often vocalise more, especially at night
Heat — unspayed female cats in heat meow persistently and loudly

If vocalisation has changed suddenly or is occurring at night in an older cat, a vet visit is worthwhile.

Scratching

Scratching serves three purposes: it maintains claw condition, stretches muscles, and deposits scent from glands in the paws. It is not spite or bad behaviour — it is a physical need.

What helps:

Provide appropriate scratching surfaces (both vertical and horizontal; some cats prefer one over the other)
Place scratching posts near sleeping areas — cats often scratch when waking up
Use positive reinforcement to direct scratching to appropriate surfaces
Nail caps can reduce damage from cats who scratch furniture despite having posts

Zoomies

The sudden frantic sprints — often at night — are called FRAPs (Frenetic Random Activity Periods). They are a normal energy release behaviour, more common in younger cats and those who are indoor-only.

If your cat's zoomies are disrupting your sleep, increase interactive play in the evening to deplete energy before bedtime.

Signs of Stress in Cats

Cats often hide stress well. Watch for:

Overgrooming (leading to bald patches)
Under-grooming (coat becoming unkempt)
Changes in litter box use (going outside the box, straining, blood)
Appetite changes (eating more or less)
Increased hiding or withdrawal
Aggression that is new or out of character
Excessive vocalisation

Common stressors: new people or animals in the home, changes to routine, home moves, building work, other cats outside.

When Behaviour May Indicate a Health Problem

Several behaviours that appear behavioural can actually be medical:

Urinating outside the litter box: Often a sign of a urinary tract infection or bladder disease
Increased thirst and urination: Can indicate diabetes or kidney disease
Sudden aggression: May indicate pain
Night-time vocalisation in older cats: Hyperthyroidism or cognitive dysfunction

When in doubt, rule out medical causes first before addressing the behaviour.
