By Dr Duncan Houston
A cat rolling onto their back may feel safe without wanting a belly rub. A cat that purrs may be comfortable, but purring alone does not prove that nothing hurts.
Feline behaviour makes more sense when you look at the whole body, the situation and what is normal for that individual cat. Those observations help you respond with useful choices instead of guessing at a single signal.
Quick Answer
Cats communicate through posture, movement, sound and scent. Read several signals together, give your cat control over contact and provide safe access to food, water, litter trays, rest and play. A new change in behaviour can also reflect pain or illness, especially when eating, grooming, mobility or toileting changes.
Read signals in context
An upright tail with a loose body often accompanies a friendly approach. A low crouch, tense muscles or a tucked tail suggests discomfort or uncertainty. Ears turning sideways, skin twitching or a lashing tail can mean the current interaction needs to stop.
Pupil size changes with light as well as arousal. A single ear position or tail movement cannot tell you exactly what a cat feels. Notice whether they approach, stay relaxed, freeze or try to leave. Give them an exit before a warning escalates.
What do meows, purrs and hisses mean?
Meowing can request interaction or access to something the cat has learned you provide. A new persistent vocalisation deserves attention, especially in an older cat or alongside changes in thirst, appetite or sleep.
Purring occurs in more than one emotional or physical state, so assess posture and health as well. Hissing or growling is a request for distance. Respecting that signal helps prevent injury; punishment may increase fear and make future reactions harder to predict. Cornell’s feline aggression guidance also highlights pain and disease as possible contributors.
Scent, scratching and territory
Cheek rubbing and scratching help cats interact with their surroundings through scent as well as touch and movement. Scratching also stretches the body and maintains claws. Offer stable scratching surfaces near resting areas and places the cat already chooses, with a texture and orientation they like.
Urine marking and ordinary toileting outside the tray are not interchangeable. Neither should be dismissed as spite. Look at the pattern and arrange assessment for a new problem, because discomfort and environmental factors can overlap.
What does the behaviour call for?
| What you notice | What it means | What to do and when |
|---|---|---|
| Cat approaches with a loose body, then moves away | An invitation followed by a choice to stop | Offer brief contact and let them leave. |
| Hiding or tension around a specific visitor or animal | The situation may feel unsafe | Provide separation, a retreat and gradual introductions. |
| New overgrooming, reduced jumping or unusual irritability | Pain, itch or illness may be involved | Arrange a veterinary examination. |
| Repeated straining with little or no urine | Possible urinary obstruction | Seek emergency veterinary care now. |
Build a home that supports normal behaviour
The AAFP and ISFM environmental needs guidelines describe the importance of safe places, separated resources, play, predictable positive interaction and a suitable sensory environment. Translate that into routes and choices your cat can actually use.
- Provide a quiet hiding place and accessible elevated resting options. Older or less mobile cats may need steps or low alternatives.
- Separate food, water and litter resources across useful locations, especially where cats avoid one another.
- Offer short hunting-style play with toys, then allow rest. Keep loose strings and small swallowable parts out of reach.
- Maintain familiar bedding and avoid strong fragrance around key resting or toileting areas.
What else could explain a behaviour change?
Dental pain can reduce sociability, arthritis can limit jumping and itchy skin can cause repeated licking. Urinary disease may change litter tray use. In older cats, medical or sensory changes can alter activity and night-time behaviour. A stressful event and a medical condition can happen together, so an obvious household trigger does not rule out disease.
What should you do next?
- Describe the behaviour objectively: where it occurs, what happens beforehand and how long it lasts.
- Compare appetite, grooming, movement, sleep and toileting with your cat’s usual pattern.
- Make one practical change, such as opening an escape route or moving a blocked resource, and record whether normal activity improves.
- Teach desired actions in brief sessions by rewarding a small achievable step. Stop while your cat remains engaged.
- Ask for veterinary behaviour support when distress persists, cats cannot share space safely or there is a risk of injury. Seek same-day advice for poor intake or a cat that seems unwell.
Common mistakes
- Treating a belly display or purr as permission for any handling.
- Forcing a hiding cat to meet visitors.
- Using hands as prey toys or punishing scratches.
- Assuming cats sharing one food bowl must be comfortable together.
Supporting wellbeing over time
Keep routines predictable while allowing individual preferences. Review resource access as cats age or household membership changes. Regular health checks and early attention to small changes are more useful than waiting for a dramatic behavioural crisis.
Frequently Asked Questions
Can cats be trained?
Yes. Short sessions, clear rewards and manageable steps can teach useful behaviours such as entering a carrier or approaching a mat.
Does my cat need another cat for company?
Not necessarily. Compatibility and each cat’s history matter. Another cat can add stress if introductions and resources are unsuitable.
Why does my cat show their belly but bite when I touch it?
The posture may indicate relaxation or play without inviting belly contact. Stop touching and use brief contact in areas your cat willingly offers.
Understanding your cat starts with observing choices and changes. A comfortable home and respectful interaction make those signals easier to read, while veterinary assessment helps when behaviour reflects a health problem.
