What limping can look like
A limping cat may hold a paw off the ground, put less weight on one leg, walk with a stiff or uneven gait, or hop. Some cats limp only after resting, or only when they jump. Others keep moving normally but lick or guard one limb. Because cats hide discomfort, a mild limp can mean a meaningful problem. Our guide to the signs a cat is in pain lists other changes that often come with it.
Common causes of limping in cats
Paw and claw problems
Many limps start at the foot. Possible causes include a thorn, splinter or piece of glass in a pad, a cut, a torn or ingrown claw, a burn from a hot surface or chemicals, an insect sting, or an infection between the toes. See common cat paw problems for more detail.
Sprains and strains
Jumping, rough play or a bad landing can strain a muscle or tendon. Mild soft tissue injuries often cause a limp that improves over a day or two, but it can be hard to tell a minor strain from a fracture without an exam.
Bites, scratches and abscesses
Cat fights can cause puncture wounds that look small on the surface. Bacteria can become trapped under the skin and form an abscess, which is a painful, swollen pocket that may cause limping if it is on or near a leg. The fur can hide the wound, so feel gently along the limb. Our guide to cleaning a cat wound explains what is reasonable at home and which wounds need a vet.
Fractures and dislocations
Falls, car accidents and other trauma can break a bone or dislocate a joint. Signs may include not using the leg at all, swelling, a leg that looks bent or at an odd angle, and severe pain. This needs prompt veterinary care.
Arthritis and joint disease
Arthritis is common in older cats and often shows up as stiffness, reluctance to jump and a limp that comes and goes. It may be gradual, so owners sometimes put it down to age. Your vet can discuss diagnosis and safe pain management.
Nerve and neurological causes
Problems affecting the spine or nerves can cause weakness, dragging a paw, knuckling over on the foot, or trouble walking, particularly on the back legs. These signs warrant a vet exam.
Sudden back leg weakness: an emergency
A sudden inability to use one or both back legs, particularly with severe pain, crying out, cold paws or paws that look pale or bluish, can indicate a blood clot blocking circulation to the limbs (often called a saddle thrombus). This is an emergency. Do not wait to see if it improves, and contact an emergency vet immediately.
How to check your cat at home
If your cat is calm and allows it, you can gently examine the leg. If your cat is in obvious severe pain or becomes aggressive, stop and call a vet instead.
- Watch your cat walk on a flat surface to see which leg is affected.
- Starting at the toes, look at each pad and between the toes for cuts, swelling, redness or debris.
- Check each claw for tearing, bleeding or curling into the pad.
- Feel along the leg for heat, swelling or lumps, comparing it with the other side.
- Gently flex the joints only if your cat tolerates it. Stop if there is any pain.
Gently remove a small, obvious splinter only if it is easy and your cat is calm. Do not dig around or force anything.
Can you treat a sprained leg at home?
For a mild limp where your cat is otherwise bright, eating and using the leg a little, vets often suggest resting your cat in a small, quiet space for a day or two, limiting jumping and watching closely. Keep food, water and a litter box close by. Never give human painkillers, as many are dangerous to cats.
If the limp does not clearly improve in 24 to 48 hours, gets worse, or you are unsure whether it is a sprain or something more serious, book a vet visit. It is hard to rule out a fracture or joint injury by looking.
When to see a vet
Contact your vet the same day, or go to an emergency clinic, if you notice:
- Your cat will not put any weight on the leg
- Swelling, a deformed limb or an obvious wound
- Sudden weakness or dragging of the back legs
- Crying, hiding or aggression when touched
- Fever, lethargy or loss of appetite
- A limp that lasts more than a day or two or keeps coming back
Trouble walking on the back legs can have many causes, including injury, arthritis, nerve problems and circulation problems, so this is best assessed promptly rather than watched for long.
What the vet may do
Your vet will usually examine the limb and joints and ask about your cat’s history, including any falls, fights or outdoor access. Depending on the findings, they might recommend X-rays, blood tests, or sedation to examine a painful limb. Treatment depends on the cause and may include wound care, antibiotics for infection, pain relief prescribed for cats, rest, surgery for some injuries, or long-term joint management.
Common questions
Why is my cat limping but not in pain?
Cats may not show obvious pain even when something hurts. A cat that limps but seems comfortable may still have an injury or a condition such as arthritis, so a limp is worth monitoring and checking if it persists.
Why is my cat limping all of a sudden?
Sudden limping often follows a minor injury, a claw or paw problem, or a bite wound, but it can also be a sign of a serious problem such as a fracture or a circulation emergency. Check the paw, and see a vet if it does not settle quickly.
Is a limping cat always an emergency?
Not always, but treat it as urgent if your cat will not bear weight, has a swollen or deformed limb, has lost use of the back legs, or seems very unwell.
How can I tell when a cat’s body is shutting down?
There is no single sign. Persistent refusal of food and water, severe weakness, trouble breathing, collapse or not responding normally are reasons to seek urgent veterinary advice rather than wait.
