Understanding Cat Behaviour: A Practical Guide
Key takeaways
- Most 'bad' behaviour is normal cat behaviour in the wrong place; the fix is usually to meet the need, not to punish the cat.
- Body language, ears, tail, posture, and eyes, tells you far more about how a cat feels than the sounds it makes.
- A sudden change in behaviour can be a sign of illness or pain, so rule out medical causes with your vet before treating it as purely behavioural.
- Scratching, climbing, hiding, and hunting are needs, not faults; provide outlets and a predictable environment and most problems ease.
Most cat “behaviour problems” are normal cat behaviours happening somewhere we’d rather they didn’t. Cats scratch, climb, hide, and hunt because they’re cats. When you meet those needs and keep their world predictable, the problems usually shrink. This is the hub for our Cat Behaviour articles.
Read the body, not the meow
A cat’s body tells you how it feels:
- Ears flat or swivelled back signal fear or irritation; forward and relaxed means calm.
- Tail held up is a friendly greeting; puffed up means fear; a fast swish means agitation.
- Posture that’s loose and open is relaxed; crouched, tense, or trying to look big means stress.
- Eyes with a slow blink are a sign of trust; hard staring and wide pupils mean arousal.
Vocalising matters too, but body language is the more reliable guide.
Rule out pain and illness first
A sudden change in behaviour deserves a vet visit before anything else. Litter accidents, new aggression, hiding, or over-grooming are often the first outward sign of a medical problem such as pain or a urinary condition. See our cat health guide for the wider picture.
Common problems and the real fix
- Litter-box trouble: clean trays, the right type and place, one per cat plus a spare, and a vet check.
- Scratching furniture: redirect to posts and pads, don’t punish.
- Aggression: identify the trigger (fear, play, redirected, territory) and reduce it rather than confronting the cat.
- Anxiety and stress: predictable routines, safe hiding spots, vertical space, and a calm introduction to any change.
Give cats outlets
Daily play that mimics hunting, scratching surfaces, places to climb and perch, and a quiet retreat go a long way. A bored or stressed cat finds its own outlets, and we usually don’t like the ones it picks. For indoor cats especially, enrichment is part of good care.
This guide is general information. Persistent or severe behaviour problems are worth discussing with your vet, who can rule out medical causes and refer you to a qualified behaviourist if needed.

Frequently asked questions
Why is my cat suddenly behaving differently?
A sudden change, hiding, aggression, litter accidents, or over-grooming, can be the first sign of illness, pain, or stress. Before treating it as a behaviour problem, have your vet check for a medical cause. Once health is ruled out, look at what changed in the environment, since cats are very sensitive to disruption.
How do I stop my cat scratching the furniture?
Scratching is a natural need, for claw care, stretching, and marking, so the goal is to redirect it, not stop it. Provide sturdy scratching posts and pads near the spots your cat already uses, make the furniture less appealing, and reward use of the posts. Never punish scratching; it only adds stress.
Why won't my cat use the litter box?
Common reasons are a tray that's too dirty, the wrong type or location, too few trays in a multi-cat home, or stress, and sometimes a medical problem such as a urinary condition. Start with a vet check, then make the tray clean, quiet, and easy to reach, with one tray per cat plus one spare.
Do cats misbehave out of spite?
No. Cats do not act out of spite or revenge; that is a human idea. What looks like spite, such as toileting outside the tray or scratching the sofa, is almost always a normal need going unmet, stress, or a medical problem. The fix is to find the cause, not to punish the cat.
Should I punish my cat for bad behaviour?
No. Punishment does not teach a cat what you want, and it usually increases fear and stress, which makes behaviour worse and damages your bond. Reward the behaviour you want, remove the triggers, and provide proper outlets such as scratching posts and daily play instead.
