Your Cat Is Limping — Here's What Could Be Going On
Cats are exceptionally good at hiding pain, so if your cat is visibly limping, something is definitely bothering them. The good news: many causes of cat limping are minor and resolve with rest. If your cat is still putting some weight on the leg, eating normally, and the limp came on gradually, you can usually monitor at home for 24 to 48 hours. The quick rule: a cat that suddenly cannot bear weight on a leg, has a leg that looks bent or swollen, or is hiding and refusing to move needs a vet visit today. For outdoor cats or cats that had a fall, limping combined with a wound, swelling, or warmth in the leg should be seen promptly. For a mild limp in an indoor cat that is otherwise acting normal, restrict jumping and climbing for a couple of days and see if it improves.
How Serious Is It?
See a vet NOW if…
- Your cat is completely non-weight-bearing — holding the leg up and not putting it down at all
- The leg looks visibly deformed, swollen, or is hanging at an abnormal angle
- There is an open wound, puncture, or abscess on the leg that is draining or hot to the touch
- Your cat is hiding, not eating, and seems to be in severe distress
- The limping started after a fall from a significant height or being hit by a car (even if the cat seems okay otherwise — internal injuries are common)
- You notice sudden onset of back leg paralysis or dragging — especially in a cat with no trauma history (possible saddle thrombus, which is a life-threatening emergency)
Schedule a vet visit if…
- The limp has not improved after 48 hours of rest
- Your cat is limping on and off over several weeks
- There is mild but persistent swelling around a joint
- Your cat is an outdoor cat and you notice a gradually worsening limp with localized warmth (possible bite wound abscess developing)
- The limping is accompanied by increased stiffness or reluctance to jump
- Your senior cat has gradually become less active and avoids heights they used to reach easily
Likely okay to monitor if…
- Your cat landed awkwardly from a jump and is mildly favoring one leg but still walking
- The limp is very subtle — slightly shorter stride on one side — and your cat is otherwise normal
- You found a minor scratch or slightly overgrown claw causing discomfort
- Your cat is still eating, grooming, using the litter box, and engaging with you
- Restrict jumping and climbing for 24 to 48 hours. If the limp does not improve, schedule a vet visit
Common Causes
Soft Tissue Injury (Sprain or Strain)
Cats are agile, but they can still land wrong. A misjudged jump, a slip off a counter, or rough play with another cat can strain a muscle or sprain a ligament. This is one of the most common causes of sudden limping in indoor cats. The leg usually looks normal with no visible swelling or deformity. Most soft tissue injuries improve with 2 to 3 days of restricted activity. If the limp does not improve with rest, a vet should evaluate it.
Bite Wound Abscess
Extremely common in outdoor cats or multi-cat households. Cat bites inject bacteria deep under the skin. The wound seals over and an abscess forms over 2 to 5 days. Your cat may limp and the area will become swollen, warm, and painful. Eventually the abscess may rupture and drain foul-smelling pus. Bite wound abscesses need veterinary treatment — antibiotics and often lancing and draining the abscess. Do not try to treat a deep abscess at home.
Arthritis (Degenerative Joint Disease)
Far more common in cats than most owners realize — studies suggest over 90 percent of cats over 12 years old have some degree of arthritis. Cats with arthritis do not always limp obviously. Instead, they stop jumping to high places, hesitate on stairs, become less playful, and may have trouble getting in and out of the litter box. If your senior cat has gradually slowed down and occasionally favors a leg, arthritis is the most likely explanation.
Fracture
A broken bone causes sudden, severe non-weight-bearing lameness. In cats, fractures most commonly happen from falls (high-rise syndrome), being hit by a car, or getting a limb caught in something. The leg may look swollen, bent, or hang unnaturally. Cats may also suffer pelvic fractures from car trauma, which cause back leg lameness and difficulty posturing to use the litter box. Any suspected fracture needs immediate veterinary care.
Overgrown or Ingrown Claw
A surprisingly common and easily missed cause of limping, especially in older or indoor cats. Without regular wear from outdoor surfaces, claws can grow long enough to curve into the paw pad, causing pain and infection. Check all claws, including the dewclaws on the inner front legs — these are the most commonly affected. Trimming the claw and cleaning the wound is often all that is needed, but if the area is infected, your vet may prescribe antibiotics.
Saddle Thrombus (Aortic Thromboembolism)
A medical emergency that typically affects cats with underlying heart disease. A blood clot lodges at the base of the aorta where it splits to supply the back legs, cutting off blood flow. The cat suddenly cannot use one or both back legs, may cry out in pain, and the affected legs feel cold and stiff. The paw pads may appear pale or blue. This is a life-threatening emergency requiring immediate veterinary attention.
What to Do Right Now
- 1
Check the paws and claws — look at the paw pads for cuts, swelling, or objects stuck between the toes. Check every claw, including the dewclaws. Overgrown or ingrown claws are a common and fixable cause of cat limping.
- 2
Restrict activity for 24 to 48 hours — keep your cat in a smaller room with low furniture. Remove access to cat trees, high shelves, and stairs. The goal is to prevent jumping and climbing while the leg rests.
- 3
Observe how they move — which leg is affected? Do they hold it up completely or just favor it? Is it a front or back leg? Does it seem worse after rest or after activity? This information will help your vet if you need a visit.
- 4
Feel gently for heat or swelling — compare the affected leg to the other side. Warmth, swelling, or tenderness in a specific area narrows down the cause. Stop immediately if your cat shows signs of pain.
- 5
Do not give human pain medication — ibuprofen and acetaminophen (Tylenol) are extremely toxic to cats and can be fatal even in small doses. Never give any human medication to a cat without explicit vet guidance.
- 6
Reassess after 48 hours — if the limp is improving, continue rest for a few more days. If there is no improvement or it is getting worse, schedule a vet visit.
Frequently Asked Questions
Why is my cat limping but not in pain?
Cats are hardwired to hide pain — it is a survival instinct from their wild ancestors. A limping cat that purrs, eats, and seems relaxed is still in some degree of discomfort. Purring in particular is not always a sign of happiness in cats — they also purr when stressed or in pain as a self-soothing behavior. Watch for subtle signs: less jumping, sleeping more, grooming the affected leg excessively, or being less social. Any limp that lasts more than a couple of days should be evaluated, even if your cat seems otherwise fine.
When should I take my cat to the vet for limping?
Go immediately if your cat cannot bear weight on the leg, the leg looks deformed, there is an open wound or abscess, or your cat is hiding and refusing to eat. Also go immediately if your cat suddenly loses the ability to use one or both back legs — this could be a saddle thrombus, which is an emergency. Schedule a visit within a day or two if the limp has not improved with 48 hours of rest or keeps coming back. A mild limp in a cat that is eating, using the litter box, and otherwise acting normal can be monitored for 24 to 48 hours.
Why is my cat limping on the front leg?
Front leg limping in cats is most commonly caused by a paw injury, overgrown or ingrown claw, a soft tissue strain from a bad landing, or a bite wound abscess. In younger cats, rough play injuries are common. In older cats, elbow or shoulder arthritis can cause front leg limping that is worse after long periods of rest. Check the paw and claws first — this is the simplest cause and the easiest to fix.
Why is my cat limping on the back leg?
Back leg limping in cats is often caused by a sprain from jumping, hip or knee arthritis in senior cats, a bite wound abscess (especially in outdoor cats), or less commonly a fracture. In cats with heart disease, sudden onset of back leg weakness or paralysis is a medical emergency (saddle thrombus). If your cat suddenly cannot move one or both back legs and the legs feel cold, get to a vet immediately. For gradual back leg limping in an older cat, arthritis is the most common cause.
My cat is limping after a jump — should I worry?
An awkward landing from a jump is one of the most common causes of sudden limping in cats. If your cat is still putting some weight on the leg and is otherwise acting normal — eating, using the litter box, and alert — you can restrict their activity and monitor for 24 to 48 hours. Most mild sprains from bad landings improve with rest. If the limp does not improve after two days, the leg is swollen, or your cat stops eating, schedule a vet visit.
How can I tell if my cat's leg is broken or just sprained?
A broken leg usually causes complete non-weight-bearing lameness — your cat will hold the leg up and refuse to put it down. There may be visible swelling, deformity, or an abnormal angle to the leg. A sprained leg is usually still partially weight-bearing — your cat favors it but can still walk. Your cat may also lick or guard the area. However, the only way to know for certain is with a veterinary exam and X-rays. If you suspect a fracture — especially if there is visible deformity or your cat is in severe distress — see a vet right away.
