Signs of Pain in Cats: What Changes to Record

What are the signs of pain in cats?

The most useful sign of pain in a cat is often a change from that cat's normal behavior. Watch for less jumping, a stiff or hunched posture, reduced grooming, eating less, altered sleep or toileting, hiding, less interaction, or a new reaction to touch. Record exactly what changed, when it began and what makes it better or worse, then see your vet. Do not diagnose the cause or give pain medicine at home.

One behavior cannot confirm or rule out pain. A cat may hide because of pain, fear, household stress or another health problem. A cat may also keep eating or purring while uncomfortable. The useful question is not simply, "Does my cat look painful?" It is, "What can my cat do comfortably today that was easy and routine before?"

Why is a change from normal so important?

Cats do not all show discomfort in the same way. A normally social cat who stops joining the household has changed. A private cat who spends the day in a familiar quiet place may not have. That is why your knowledge of the individual cat matters.

The Feline Veterinary Medical Association says caregiver observations are central to chronic pain assessment because changes can be subtle and gradual. The American Animal Hospital Association similarly notes that a slow decline can be missed when it is mistaken for ordinary aging.

Think back to a specific recent baseline rather than an idealized younger cat. Compare this week with last week or this month with two or three months ago. For a senior cat, our senior cat care guide explains which routine changes deserve closer attention. New changes still belong with a veterinarian; they should not be dismissed as age.

Which movement changes should you record?

Watch ordinary movements your cat chooses without prompting. Useful examples include:

• pausing before jumping onto a familiar chair;
• jumping to a lower surface first instead of taking the usual route;
• pulling up with the front legs rather than pushing evenly from behind;
• landing heavily, slipping or hesitating on stairs;
• walking stiffly after sleep;
• moving less often between normal resting places;
• avoiding a high-sided litter box or a frequently used cat flap;
• stopping play sooner than usual.

Do not make the cat jump, climb stairs or repeat a movement to prove there is a problem. Never bend, squeeze or press a sore-looking limb or joint. If a movement happens naturally and it is safe to do so, a short video from the side can give the veterinary team useful context. AAHA includes owner videos and photos among the information that can help with pain assessment.

Write down the exact task and the change. "Paused for eight seconds before the sofa and used the footstool" is more useful than "seems slow." The number is an observation from that event, not a pain score.

What posture and resting changes can suggest discomfort?

A painful cat may rest in a hunched or tense posture, hold the head lower, change how weight is distributed, or have difficulty settling. Some cats sleep more or choose an unusual hiding place. Others keep changing position because they cannot get comfortable.

International Cat Care's guide for cat carers lists changes in normal behavior, unusual hiding, a hunched resting posture, reduced movement and reluctance to jump among possible signs of acute pain. These observations still do not identify the cause.

Take a photograph only if you can do it without moving, cornering or delaying care. Record whether the posture appears after a particular activity, is present after waking, or persists throughout the day. If the cat cannot settle, seems severely distressed or has just had a major injury, contact an emergency veterinary clinic promptly.

How can grooming change when a cat is in pain?

Reduced grooming can leave the coat looking clumped, greasy or less orderly than usual. A cat may stop reaching an area that requires twisting or balance. Record the location and whether the change is new; do not tug at mats or force the cat into a grooming position to inspect it.

Grooming changes have several possible causes, including problems unrelated to pain. See your vet about a new or persistent change rather than assuming the cat is sore or simply untidy. If you can safely observe without touching, note which areas the cat still grooms and which are avoided.

What appetite and drinking changes matter?

Record a change in how much the cat eats, how quickly eating begins, whether food is dropped, and whether the cat approaches the bowl but turns away. Use the amount actually served and the amount left rather than "some" or "hardly any" when practical. Also record a clear change in drinking, but do not restrict water.

Eating less can accompany pain, but it can also signal many other health problems. It is not a home test for pain. See your vet promptly if a cat is eating less or stops eating, and follow the practice's timing advice. Do not try a prescription diet, supplement or appetite medicine unless the veterinary team directs it.

Which litter-box changes should you notice?

Pain may change how a cat approaches, enters or positions in the litter box. Watch for:

• a new pause at the box entrance;
• choosing a lower-sided box when several are available;
• difficulty squatting or maintaining position;
• eliminating close to, rather than inside, the box;
• fewer or more visits than usual;
• crying, straining or repeated attempts.

Do not label an accident as spite or a training failure. Record urine and stool observations you can make without disturbing the cat, then see your vet about any new toileting change. Repeated straining, distress in the box, or attempts that produce little or no urine require urgent veterinary contact. Cornell's feline lower urinary tract disease guide describes suspected urethral obstruction as a true medical emergency requiring immediate veterinary attention.

How can interaction and temperament change?

A cat in pain may hide, spend less time with people or other animals, stop greeting the household, or avoid being picked up. A new hiss, swat, growl or bite when approached or touched can also be a protective response. Other cats become unusually quiet or seek more reassurance.

Use our cat body-language guide to describe ears, eyes, tail and body position, but do not use one signal as a diagnosis. Give the cat space and avoid the action that prompted the reaction. A sudden behavior or temperament change is a health concern: see your vet.

Keep children and other animals away from a cat who is guarding space or reacting to touch. This reduces stress and avoids another painful interaction while veterinary advice is arranged.

Do facial expressions show that a cat is in pain?

Squinting, a tense face or a changed ear and head position can occur with pain. Veterinary teams may use validated assessment tools that combine facial and behavioral observations. These tools support a clinical assessment; they do not turn one photograph into a diagnosis.

Do not wait for a dramatic facial expression before acting on a clear functional change. Do not repeatedly photograph or approach a cat who is distressed. Record what you noticed and share it with the veterinary team.

How should you keep a useful pain-observation log?

Choose three to five ordinary activities that matter to your cat. They might be getting onto a particular chair, using the litter box, walking to the food area, grooming the lower back, or joining an evening routine. Use the same activities for each check so the comparison remains meaningful.

For every change, record:

• date and time;
• the exact activity or behavior;
• what the cat did, in plain descriptive words;
• where it happened and on what surface;
• whether it followed rest, play, eating or toileting;
• appetite, drinking, grooming and litter-box changes that day;
• any medication already prescribed and when it was given;
• a short video or photo, only when safe and natural;
• who you contacted and the instructions received.

Avoid assigning your own pain number unless your veterinarian has given you a specific validated tool and shown you how to use it. "Did not jump to the windowsill on three natural opportunities" is clearer than "pain 7 out of 10." Preserve the raw observation even if the cat later seems more comfortable.

What can you change while waiting for veterinary advice?

Keep essential resources easy to reach. Put food, water, a comfortable resting place and an accessible litter box on the same level when stairs appear difficult. Add secure non-slip surfaces to routes the cat already uses, keep the routine calm, and provide a quiet place away from children and other animals.

These are temporary access and comfort measures, not treatment. Do not force exercise, stretch limbs, massage a painful area, or test a jump. Do not make a sudden diet change. If a shelf, ramp or step requires structural fixing, use a qualified installer; an unstable aid can create another injury risk.

The FelineVMA's patient-support guidance recommends predictable routines, safe places and easier access to resources as part of an individualized veterinary plan. Ask the veterinary team which changes suit your cat's condition and mobility.

What should you tell the veterinary practice?

Start with the change, its timing and its effect on ordinary function. A concise call might be: "Since yesterday evening, she has stopped jumping to her usual chair, walks stiffly after getting up, and ate about half her normal breakfast. I have a 20-second video of her walking."

Also provide the cat's age, relevant diagnoses, current medicines and supplements, recent falls or injuries, and whether urine and stool output changed. Do not stop, increase, repeat or combine prescribed medicine unless the veterinary team tells you to do so.

Our broader cat illness warning-sign guide can help you organize other changes. The veterinary practice decides how soon the cat needs examination and which tests or treatment are appropriate.

When is pain an emergency?

Call an emergency veterinary clinic promptly for severe distress, collapse, breathing difficulty, a major fall or other trauma, a burn, an eye injury, or pain accompanied by repeated straining with little or no urine. Follow the clinic's transport instructions and minimize handling.

Do not delay urgent care to complete a log, capture a better video or see whether the cat improves. Do not offer a human painkiller or medicine prescribed for another animal. The US Food and Drug Administration says human medicines should not be given unless a veterinarian directs it and warns that acetaminophen can be fatal to cats.

For a less dramatic but new change in movement, posture, grooming, appetite, sleep, toileting or interaction, see your vet. Early, specific observations are useful. Home diagnosis and medication are not.
