To check cat health at home, calmly observe breathing, appetite, drinking, toileting, movement, grooming and behaviour, then look at the eyes, ears, mouth, coat, skin, paws and body only if your cat is comfortable. Record changes from your cat’s normal pattern and arrange veterinary assessment when something is new, persistent or worsening. A home check can reveal useful clues; it cannot diagnose disease or replace an examination.
Stop checking and seek urgent veterinary help for open-mouth or difficult breathing, collapse, seizures, blue or pale gums, severe pain, major trauma, suspected poisoning, repeated vomiting, sudden inability to walk, or straining or inability to urinate. Do not delay care to finish a checklist or take a video.
What a home health check can—and cannot—tell you
The most useful home check answers three questions:
- What is normal for this cat?
- What has changed, when did it start and is it progressing?
- Does the cat need urgent care, a prompt appointment or routine follow-up?
Cats may mask discomfort, and a shiny coat or normal appetite does not rule out illness. Home observation cannot measure blood pressure accurately without appropriate equipment and training, examine internal organs, assess every tooth, or replace blood and urine testing when those are indicated. Even a checklist with every box marked “normal” is not a clean bill of health.
Use your observations to give the vet better information, not to label the cause yourself. Many different conditions can produce the same change in thirst, weight, behaviour or mobility.
Before you begin: keep the check calm
Choose a quiet time when your cat is relaxed. Start by watching without touching. Keep the session brief, use a familiar resting place and allow the cat to leave. PDSA advises taking home checks slowly and stopping if a pet is worried or stressed.
Do not forcibly restrain your cat, prise open the mouth, press painful areas or persist with ear, paw or belly handling. Flinching, tension, attempts to escape, growling or swatting are reasons to stop. Stress can alter breathing and behaviour, making your observations harder to interpret.
Unless your vet has specifically trained you and asked you to monitor them, avoid routine rectal temperatures, pulse taking, blood-pressure attempts, skin-pinching tests or capillary-refill checks. A poorly performed measurement can create false reassurance or unnecessary alarm. If something concerns you, contact the vet rather than trying more invasive checks.
Step 1: Observe before touching
Watch your cat walk, rise, jump, eat, rest and use the litter tray during ordinary routines.
| Observe | Useful changes to record |
|---|---|
| Breathing | Effort, persistent change in rate or pattern, wheezing, open-mouth breathing or abdominal effort |
| Movement | Limping, stiffness, hesitation, lower jumps, use of intermediate surfaces or difficulty rising |
| Behaviour | Hiding, withdrawal, irritability, confusion, altered sleep, vocalisation or less play |
| Eating and drinking | Actual food eaten, chewing changes, dropped food, increased or reduced thirst |
| Litter use | Urine clump size and frequency, stool consistency, accidents, discomfort or repeated unproductive visits |
| Grooming | Reduced grooming, matting, overgrooming, bald patches or overgrown nails |
Take a short video only when safe and if it will not delay care. Note the date, time and what happened before and after. A video can help the vet assess intermittent gait, eating or behaviour changes that may not appear in the clinic.
Step 2: Check the head without forcing handling
If your cat already accepts gentle handling, look briefly at the following. Otherwise, observe what you can during normal interaction and leave closer examination to the veterinary team.
Eyes
Look for your cat’s usual openness and clarity. Note new redness, cloudiness, squinting, discharge, swelling, unequal pupil appearance or signs of impaired navigation. A painful or suddenly changed eye needs prompt veterinary advice; do not apply leftover drops or human eye products.
Ears
Notice odour, visible discharge, redness, swelling, head shaking, scratching or sensitivity. Do not insert cotton swabs or cleaner deep into the ear canal. A vet should identify the cause before treatment because the correct approach depends on the problem.
Nose and breathing
Look for discharge and listen for new congestion or noisy breathing. A nose feeling dry at one moment is not enough to diagnose illness. Breathing effort and the whole cat matter more. Open-mouth breathing or marked effort is an emergency.
Mouth and eating comfort
Only look at the mouth if your cat is comfortable. Record bad breath, drooling, bleeding, pawing at the mouth, chewing on one side, dropping food or reluctance to eat. Do not scrape tartar, pull a loose tooth or force the mouth open. Dental lesions can be missed at home even when a cat continues eating.
Pale, blue or yellow gums, or gums that look markedly different from normal alongside weakness or illness, need urgent veterinary advice. Do not repeatedly press them to perform a home test.
Step 3: Coat, skin, body and paws
During gentle stroking or grooming, feel and look for:
- new or changing lumps, swellings, wounds or painful areas;
- matting, dandruff, greasy fur, bald patches or overgrooming;
- fleas, flea dirt or other visible parasites;
- reduced grooming over the back or hips;
- overgrown, broken or ingrown nails; and
- soiling around the rear or a change in tail carriage.
Do not squeeze a lump, lance an abscess or pull out an embedded object. Photograph a visible change next to a simple size reference if safe, record its location and arrange advice. A small lump cannot be identified reliably by touch alone.
If your cat resists belly, back or paw contact, stop. Reluctance itself is worth recording, but it does not prove where the problem lies.
Step 4: Weight, shape and muscle trends
There is no single healthy weight for every cat. Compare weight, body condition and muscle condition over time, ideally with veterinary assessment. A stable scale weight can conceal muscle loss, and a fluffy coat can hide gradual weight change.
If your vet agrees that home weighing is appropriate:
- Use the same scales and comparable time and conditions.
- Weigh yourself, then yourself holding the cat if the cat is comfortable; subtract the first reading from the second. Alternatively, use a suitable carrier with a tare method.
- Keep handling brief and stop if the cat becomes distressed.
- Record the result and trend rather than reacting to one minor fluctuation.
Do not start a restrictive diet based on a home reading. Unexplained loss or gain, reduced muscle or a changed appetite deserves assessment. Your vet can determine a safe target and plan for the individual cat.
Step 5: Food, water and litter output
Daily routines often reveal more than a hands-on examination.
Food and water
Record what is actually eaten, especially in multi-pet homes. Note changes in preference, speed, chewing and water intake. Increased thirst or urination is not something to diagnose from bowl level alone: evaporation, spills and other pets can distort the amount. Report the pattern to your vet.
Wet food can contribute water, but it does not replace fresh water or investigation of thirst and urination changes. See our cat hydration guide and wet-food hydration guide for practical background. If kidney disease has already been diagnosed, our senior-cat kidney-disease home-care guide explains monitoring and veterinary treatment support.
Urine and stool
Regular litter cleaning helps you recognise your cat’s usual clump size, frequency and stool consistency. Record diarrhoea, constipation, blood, accidents or repeated tray visits. Straining or passing little or no urine is an emergency, particularly in male cats; do not mistake it for constipation or wait for a home remedy to work.
House-soiling can be associated with pain, urinary or gastrointestinal disease, mobility problems, stress or tray access. Punishment is inappropriate and will not address the cause.
Four signs your cat may be suffering
Rather than relying on one dramatic symptom, look across these four broad groups:
- Loss of normal behaviour: hiding, withdrawal, irritability, reduced play or altered interaction.
- Changed maintenance behaviour: reduced appetite, altered grooming, changed sleep or altered drinking.
- Changed movement or posture: stiffness, reluctance to jump, hunching, restlessness or touch sensitivity.
- Changed elimination or breathing: house-soiling, toileting discomfort, abnormal stool, or altered breathing pattern.
These are warning categories, not a four-item diagnosis or a rule that suffering exists only when all four appear. One severe sign can be enough for urgent care. Subtle changes also deserve attention. Our senior cat dementia guide explains why behaviour changes should not automatically be attributed to ageing or cognition.
How often should you check your cat at home?
PDSA suggests a gentle nose-to-tail check at least a couple of times a week. In practice, the right routine is one your cat tolerates without stress. Brief daily observation during feeding, play and litter cleaning can sit alongside a slightly more deliberate visual check.
Routine veterinary examinations remain important even when home observations seem normal. The appropriate examination and screening schedule depends on age, history, existing conditions and medicines. Older cats and cats with chronic conditions may need closer monitoring; see our senior cat care guide.

What to do with a concern
Emergency now: breathing difficulty, open-mouth breathing, collapse, seizures, severe pain, blue or pale gums, major trauma, suspected poisoning, sudden inability to walk, or straining or inability to urinate.
Prompt veterinary advice: repeated vomiting, marked lethargy, sudden confusion, not eating, a painful eye, rapidly worsening signs or any situation that worries you. The clinic can determine urgency.
Arrange assessment: persistent or progressive weight, appetite, thirst, toileting, grooming, mobility, sleep, skin or behaviour changes. Do not wait for the next routine visit if the pattern is changing.
Keep your regular and after-hours veterinary numbers accessible. Do not give human medicines, another pet’s prescription, essential oils or a new supplement to treat an undiagnosed sign.
Frequently asked questions
How do I know if my cat has health problems?
Look for changes from their normal appetite, weight, thirst, toileting, grooming, movement, sleep and interaction. These signs are not specific to one disease, so a vet must interpret them alongside an examination and any indicated testing.
What does a wellness check for a cat involve?
At home, it involves calm observation and a gentle visual check, plus records of weight, intake, output and behaviour. A veterinary wellness visit adds a hands-on examination, preventive care and screening chosen for the individual.
Can I check my cat’s blood pressure at home?
It is not a routine owner check. Accurate measurement needs suitable equipment, technique and interpretation, and stress affects readings. Ask your vet to perform it and advise whether any specific home monitoring is appropriate.
Should I take my cat’s temperature at home?
Not unless your vet has trained you and asked you to do it. Handling can be stressful and an untrained reading may mislead. Contact the vet based on the cat’s signs rather than delaying for a temperature.
Is a dry nose a sign my cat is sick?
Not by itself. Look at the whole cat and record discharge, breathing changes, appetite, behaviour and other signs. Breathing difficulty requires urgent attention regardless of nose moisture.
