Cat Arthritis: How to Tell If Your Cat Is in Pain
By Dr. Zubair Khalid, DVM, MS, PhD ·

Key Takeaways
- Feline arthritis (osteoarthritis) is a progressive degenerative joint disease characterized by cartilage wear, leading to inflammation and pain, most commonly affecting hips, knees, elbows, and the spine.
- Cats mask pain due to predatory instincts, manifesting subtle behavioral changes such as altered litter box habits, reduced grooming, new sleeping locations, irritability, and decreased play, rather than overt limping.
- Urgent veterinary attention is required for sudden inability to use hind legs, dragging limbs, crying when touched, joint swelling/heat, fever, or collapse, as these may indicate life-threatening conditions like blood clots or fractures.
- Early recognition and diagnosis of arthritis are critical for effective pain management, which can involve weight management, joint supplements, prescription analgesics, and environmental modifications to improve comfort and slow disease progression.
- Never administer human analgesics (e.g., acetaminophen, ibuprofen) to cats, as they are highly toxic and can cause severe organ damage or death due to differences in feline drug metabolism.
- A veterinary visit typically includes a thorough physical examination, assessment of range of motion, and potentially bloodwork and X-rays (often with sedation) to confirm diagnosis, rule out other conditions, and stage the severity of arthritis.
Cats hide pain better than almost any other animal. In the wild, showing weakness makes a cat vulnerable, so your cat's instincts tell her to mask discomfort until it becomes severe. This means you may not see obvious limping or crying out. Instead, arthritis pain often shows up as small changes in daily habits: sleeping in new places, missing the litter box, or no longer jumping onto the couch.
The good news is that you can learn to spot these changes. Arthritis, also called osteoarthritis, is a progressive wearing down of the cartilage that cushions the joints. It is common in older cats, but it can start in middle age. Catching it early matters because pain management works best when it begins before the joint damage becomes severe. If you notice any of the signs described below, a veterinary visit is the right next step. Your veterinarian can confirm whether arthritis is the cause and start a treatment plan that keeps your cat comfortable.
Is This an Emergency?
Most arthritis pain is not an emergency, but some signs can point to a more urgent problem. Use this table to decide how quickly to act. When in doubt, call your veterinarian.

What Is Most Likely Going On: Arthritis Pain
Arthritis is the most common cause of chronic pain in older cats. The condition develops when the smooth cartilage that covers the ends of bones inside a joint wears thin. Without that cushion, bones rub against each other, causing inflammation, swelling, and pain. The joints most often affected are the hips, knees, elbows, and spine.
Because cats cannot tell you where it hurts, they show pain through behavior. A cat with arthritic knees may stop jumping onto the kitchen counter because the landing hurts. A cat with spinal arthritis may hiss when you pet her lower back. These are not acts of spite or laziness. They are your cat's way of protecting painful joints.
The American Animal Hospital Association's senior care guidelines note that chronic pain in older pets is frequently under-recognized because owners attribute changes to normal aging. But pain is not a normal part of aging. It is a treatable condition.
The Subtle Signs Owners Miss
Cats rarely limp with arthritis. Instead, they change their routines to avoid pain. Watch for these specific behaviors:
Litter box problems. A cat with painful hips may find it hard to squat. She may urinate just outside the box, stand while urinating, or stop covering her waste. This is often mistaken for a behavioral issue, but it is frequently a pain issue. The MSD Veterinary Manual's pet owner resources describe how joint pain can interfere with normal posture and elimination habits.
Reduced grooming. Twisting to lick the lower back or hind legs becomes painful. A cat with arthritis may develop matted fur, dandruff, or a greasy coat, especially along the back and tail base.
New sleeping spots. If your cat used to sleep on the bed but now sleeps on the floor, she may be avoiding the jump. Stiffness after rest is common, so she may also choose spots that are warm, soft, or easy to reach.
Irritability. A cat in pain may hiss, swat, or hide when touched, especially around the hips, back, or paws. She may also stop wanting to be held or brushed.
Decreased play and exploration. A cat who no longer chases toys, climbs the cat tree, or follows you from room to room may be in pain. Reduced activity is one of the earliest and most reliable signs of arthritis.
What Else Could It Be?
Several other conditions can cause similar signs, which is why a veterinary examination is necessary. These include:
Chronic kidney disease. This common condition in older cats causes nausea, weight loss, increased thirst, and reduced grooming. It can also make a cat feel generally unwell and less active. The International Renal Interest Society's staging guidelines explain how kidney disease is diagnosed and staged, and your veterinarian may recommend blood and urine tests to rule it out.
Dental disease. Painful teeth or gums can cause a cat to stop eating, drool, paw at her mouth, or become withdrawn. Dental pain does not cause the jumping hesitations or stiffness that arthritis does, but it can look similar in terms of reduced activity and irritability.
Neurological issues. Nerve problems, such as a compressed spinal disc, can cause weakness in the back legs, wobbliness, or dragging of the paws. These signs come on more suddenly than arthritis and require prompt veterinary attention.
Obesity. Excess weight puts extra strain on joints and can make arthritis worse. A heavy cat may move less simply because carrying the weight is tiring. Weight loss is often a key part of arthritis management, but it does not replace a proper diagnosis.
Why You Should Not Wait
Arthritis is progressive. The longer a cat lives with untreated joint pain, the more muscle mass she loses, and the harder it becomes for her to move. This creates a downward spiral: less movement leads to weaker muscles, which leads to more joint instability and more pain.
Early diagnosis gives you more options. Your veterinarian can recommend weight management, joint supplements, prescription pain medications, physical therapy, and changes to your home environment such as ramps and low-sided litter boxes. The American Animal Hospital Association's pet owner resources emphasize that pain management plans work best when they are tailored to the individual pet and adjusted over time.
Do not try to give your cat human pain relievers. Many human medications, including ibuprofen and acetaminophen, are toxic to cats and can be fatal. Only a veterinarian can determine which medication is safe and at what dose, because cats process drugs differently from dogs and humans. Dosing must come from the treating veterinarian, who will weigh your cat and consider her kidney and liver function before prescribing anything.
If you are seeing any of the signs in this article, start by keeping a simple diary for a few days. Note when your cat hesitates, where she sleeps, how often she uses the litter box, and whether she flinches when touched. Bring that diary to your veterinary appointment. It will help your veterinarian understand your cat's normal patterns and spot the changes that matter.
What You Can Do at Home Right Now
If your cat is showing mild signs of stiffness, you can start making small changes today. These do not replace a veterinary diagnosis, but they can reduce discomfort while you arrange a visit.
Warmth helps. A heated bed or a microwavable heat pad wrapped in a towel can ease aching joints. Place it where your cat already likes to sleep. Make sure there is always a cooler spot nearby so your cat can move away if it gets too warm.
Raise the food and water bowls. Cats with sore front legs often crouch low to eat. A shallow, raised bowl reduces strain on the neck and shoulders. You do not need a special stand. A sturdy box or a stack of books under the bowl works well.
Add ramps or steps. Cats with arthritis often stop jumping because landing hurts. A ramp up to the sofa, the bed, or a favorite window perch lets your cat move without pain. Start with a low, wide ramp with a non-slip surface. Do not force your cat to use it. Place a treat at the top to encourage exploration.
Make litter boxes easier to enter. A box with a low front edge is far easier for a stiff cat to step into. If your cat is urinating outside the box, this is often the reason. Keep the box clean and in a quiet, easy-to-reach spot. Do not move it unless you must.
Keep nails trimmed. Long nails change how a cat walks and can make arthritis pain worse. If you are not comfortable trimming nails, your veterinary team can do it.
Watch the weight. Extra body weight adds direct pressure to arthritic joints. If your cat is overweight, ask your veterinarian about a safe weight loss plan. Do not cut food suddenly. Cats can develop serious liver problems if they stop eating for even a few days.
What you must not do. Never give your cat human pain medication. Acetaminophen, ibuprofen, and naproxen are toxic to cats and can be fatal. Even a small dose can cause severe organ damage. Do not use over-the-counter pet pain relievers without explicit instructions from your veterinarian. Cats process medications very differently from dogs and people. The correct drug and dose must come from a veterinarian who has examined your cat.
What to Write Down Before You Call the Vet
Your observations are the most useful information you can bring. Write these down over two or three days before your appointment.
The symptom checklist. Print or copy this list and mark what you see.
| Sign | Yes or No | How Often | When It Happens |
|---|---|---|---|
| Hesitates before jumping | |||
| Misses a jump it used to make | |||
| Stiff when first getting up | |||
| Limps, even briefly | |||
| Reluctant to use stairs | |||
| Urinates outside the litter box | |||
| Cries or hisses when touched | |||
| Grooms less, especially on the back | |||
| Eats less or loses weight | |||
| Hides more than usual | |||
| Seems grumpy when approached |
The mobility observation guide. Pick a quiet time and watch your cat move. Do this twice a day for two days.
- The sit test. Watch your cat sit down. A cat with hip or knee pain may sit with one leg stuck out to the side. A healthy cat tucks both hind legs under.
- The walk test. Watch your cat walk across a room. Look at the hind legs. Does one leg step shorter than the other? Does the back sway from side to side?
- The jump test. Place a treat on a low chair, about 30 cm high. Watch how your cat gets down. Does it jump, or does it climb down front legs first?
- The stair test. If you have stairs, watch your cat go up and down. Cats with arthritis often pause at the bottom before climbing.
- The touch test. Gently run your hands along your cat's back, hips, and legs. Notice if your cat flinches, pulls away, or turns to look at your hand.
Record what you see in plain words. For example, "Hind legs wobble after getting up" or "Refuses to jump onto the couch, uses the step instead." These details help your veterinarian understand how the pain affects your cat's daily life.
What a Veterinary Visit Usually Involves
Your veterinarian will start by asking about the signs you have observed. They will ask when the stiffness started, whether it is worse in the morning, and whether your cat has had any falls or injuries.
The physical exam is the core of the visit. Your veterinarian will watch your cat walk, feel each joint for swelling or pain, and check the range of motion in the legs. Cats often tense up in a clinic, so the exam may be brief. That is normal.
Tests commonly considered. Many cats with arthritis are older, so your veterinarian may recommend bloodwork and a urine test to check kidney, liver, and thyroid function. These tests rule out other conditions that can cause similar signs, such as kidney disease or an overactive thyroid. The AAHA Senior Care Guidelines recommend regular blood and urine testing for senior pets because chronic conditions often develop silently.
X-rays may be offered to confirm arthritis and assess its severity. X-rays require your cat to be still, which often means light sedation. Not every cat needs X-rays, especially if the physical exam clearly points to arthritis.
What drives the cost. A basic exam with a veterinarian typically ranges from 50 to 150 dollars. Bloodwork adds roughly 100 to 250 dollars. X-rays with sedation can add 150 to 400 dollars. These are general ranges only. Prices vary widely by region and clinic, and some clinics offer senior wellness packages that bundle these tests at a lower total cost. Ask for an estimate before any testing.
Treatment options. Arthritis in cats is managed, not cured. Common approaches include prescription pain medications, joint supplements, weight management, and physical therapy. Newer injectable medications can provide longer-lasting pain relief. Your veterinarian will recommend a plan based on your cat's age, overall health, and the severity of the arthritis. Dosing for any medication must come from the treating veterinarian, because the correct amount depends on your cat's weight, kidney function, and other factors.
When an Online Vet Can Help, and When It Cannot
Some situations in this article require hands-on care. If your cat cannot stand, is dragging a hind leg, has suddenly stopped eating, or is crying out in pain, do not use a remote service. These signs can indicate a serious problem such as a blood clot, a fracture, or kidney failure, and they need in-person emergency care immediately. The AVMA pet owner resources advise seeking immediate veterinary attention for sudden collapse or severe pain.
A remote consultation is genuinely useful for early or mild arthritis signs. If your cat is slightly stiff in the morning but otherwise eating and moving well, an online vet can help you decide whether a clinic visit is needed. They can also answer questions about a medication your cat is already taking, such as whether vomiting is a known side effect, or help you track progress on a chronic condition.
A remote vet can take a detailed history, watch your cat move on video, and give advice. In many states they can prescribe medication, but prescribing rules differ by state, and a veterinarian may require an in-person examination first. What a remote vet cannot do is palpate the abdomen, listen to the chest, take a temperature, run bloodwork, or take X-rays. Those require a physical visit. If your cat needs a prescription for ongoing pain control, plan for an in-person appointment to establish that care.
Common Mistakes Owners Make
Many well-meaning owners accidentally make arthritis harder for their cat. The most common error is assuming a cat who still jumps on the counter is pain free. Cats hide discomfort masterfully, and a single daily jump does not rule out arthritis. Another frequent mistake is giving human pain relievers. Acetaminophen, ibuprofen, and aspirin are toxic to cats and can cause kidney failure or liver damage. Never give any human medication without explicit instruction from your veterinarian.
Owners also often stop treatment once the cat seems better. Arthritis is progressive, so pain returns when medication or supplements stop. A third mistake is ignoring weight. Extra pounds press on already sore joints, and many cats are overweight without their owners realizing it. Finally, some owners wait until the cat stops eating or crying out. By that stage, the pain is severe. Cats usually show much subtler signs first.
| Mistake or Myth | What to Do Instead |
|---|---|
| "My cat still jumps, so she is fine." | Watch for other changes like sleeping more, missing the litter box, or avoiding stairs. |
| "I gave my cat a baby aspirin." | Stop immediately and call your veterinarian or a pet poison helpline. Human painkillers can kill cats. |
| "He seems better, so I stopped the medicine." | Finish the full course or continue the prescribed plan. Arthritis needs ongoing management. |
| "My cat is just getting old and slow." | Slowing down is often pain, not age. Ask your vet about a pain trial. |
| "Indoor cats do not get arthritis." | Arthritis is common in indoor cats, especially as they age. |
How to Reduce the Chance of It Happening Again
You cannot cure arthritis, but you can slow its progress and reduce pain flares. Weight control is the single most effective step. Ask your veterinarian for a target weight and a measured feeding plan. Even a half pound of weight loss can noticeably improve a cat's mobility.
Provide easy access to everything your cat needs. Place food, water, and litter boxes on one level. Add a ramp or low steps to the bed or sofa. Keep nails trimmed short, since long nails change how a cat walks and put extra strain on joints. Use shallow litter boxes with a low front edge so entering is easy. Warm, soft bedding in a quiet spot helps sore joints. Gentle, regular play that does not require jumping keeps muscles strong without overloading joints. Follow the AAHA pet owner resources for guidance on life stage care and pain management.
What Recovery and Ongoing Management Usually Look Like
Arthritis has no cure, so "recovery" means finding a plan that keeps your cat comfortable. Most cats show improvement within two to four weeks of starting treatment. That plan often combines weight loss, joint supplements, prescription pain medication, and environmental changes. Your veterinarian determines the right drug and dose for your cat. Never adjust doses yourself, because cats metabolize medications differently than dogs or humans.
Some cats need a trial period of two to three weeks on a pain medication to see if their mobility improves. If the cat moves better, that confirms pain was the problem. Ongoing management means regular checkups, usually every six to twelve months, to adjust the plan as the cat ages. The AAHA Senior Care Guidelines recommend regular monitoring of chronic conditions in senior pets. Some cats do well on the same plan for years. Others need changes every few months. Expect to revisit the plan at each veterinary visit.
Frequently Asked Questions
How do I know if my cat is in pain or just old?
Age itself does not cause limping, hiding, or litter box accidents. Pain does. If your cat moves less, sleeps more, or avoids being touched, assume pain is involved until a veterinarian says otherwise. A simple pain medication trial can help tell the difference. If the cat improves on pain relief, arthritis was likely causing the behavior changes.
Can I give my cat over-the-counter joint supplements?
Some supplements are safe, but not all are equal. Glucosamine and chondroitin products made specifically for cats are generally safe, but you should still ask your veterinarian first. Some human supplements contain ingredients that are toxic to cats. Your vet can recommend a brand with proven quality and tell you the correct amount.
How often should my arthritic cat see the veterinarian?
Most cats with arthritis benefit from a checkup every six months. This lets the vet assess pain control, adjust medication, and monitor weight. Older cats often have other conditions like kidney disease, so regular blood work matters. The MSD Veterinary Manual pet owner version explains how chronic conditions interact and why monitoring is important.
Will my cat need surgery?
Surgery is rarely the first choice for feline arthritis. Most cats manage well with medication, weight control, and home changes. Surgery is reserved for specific cases like a torn ligament or severe hip disease. Your veterinarian will discuss whether surgery is an option based on your cat's age, overall health, and imaging results.
How long will my cat live with arthritis?
Arthritis itself is not fatal. Many cats live for years with good pain management. The bigger risk is that untreated pain reduces quality of life and may make the cat stop eating or grooming. With proper care, most arthritic cats continue to enjoy life well into their senior years.
My cat still plays sometimes. Does that mean the pain is not bad?
No. Cats are experts at hiding pain, and they will still have good moments. A cat who plays for five minutes may still be in pain for the other 23 hours of the day. Look at the whole picture: appetite, grooming, litter box use, and willingness to jump. If any of those have changed, talk to your veterinarian.
