Why Is My Cat Limping? Causes, First Aid and When to See a Vet

By Tailwisp Editorial TeamUpdated October 20, 20264 min read

A cat that favors a leg is telling you something hurts. But because cats hide pain, the limp may be mild even when the cause is serious. Knowing the likely causes, how to check safely and when to hurry to the vet can protect your cat.

Common causes

• Soft tissue sprain or strain, from a jump, fall or rough play.
• Paw injuries: cuts, thorns, glass, burns or a torn or ingrown claw. See how to trim cat nails.
• Bite wounds and abscesses. See cat bite wounds and abscesses.
• Fractures, after falls or road accidents.
• Dislocations, such as a hip or kneecap.
• Arthritis, common in older cats, with stiffness, especially after rest. See arthritis in cats.
• Hip dysplasia and kneecap problems, in some breeds.
• Infections, in a joint or bone.
• Blood clots, which cause sudden pain and paralysis in the hind legs. See congestive heart failure in cats.
• Nerve damage, tumors or spinal disease. See cancer in cats.
• Insect stings and bites.
• Calicivirus, which can cause temporary joint pain. See feline calicivirus and herpesvirus.

Safe checking at home

Cats in pain may bite. Move slowly, speak softly, and stop if the cat tenses, growls or tries to pull away.

1. Watch the cat walk, and note which leg, whether it is the front or back, and whether it bears weight.
2. Look at the leg and paw for swelling, redness, wounds, blood or an unnatural angle.
3. Gently check between toes, the pads and the claws for objects or cuts.
4. Feel for warmth or swelling, comparing both legs.
5. Do not try to straighten or manipulate a suspected fracture.

Use a towel for control, if safe. See how to pick up and hold a cat.

When to go straight to the vet

• The cat will not put any weight on the leg.
• The leg dangles, or looks bent or swollen.
• There is an open wound, heavy bleeding or a bone showing.
• Sudden hind-leg paralysis, with cold paws and crying out.
• Fever, lethargy or loss of appetite.
• The limp follows a fall or a car accident.
• A limp that continues beyond a day or two.

Use cat emergency warning signs as a guide.

First aid

• Keep your cat confined and quiet, to prevent more injury.
• For bleeding, apply gentle pressure with clean gauze. See cat first aid kit.
• Do not use human painkillers. Ibuprofen, naproxen, acetaminophen and aspirin are dangerous to cats. See cat poisoning: what to do.
• Do not apply creams or ointments without advice.
• Transport in a secure carrier.

Diagnosis

The vet examines the leg and joints, may sedate the cat for a pain-free exam and takes X-rays. Further tests may include bloodwork, joint fluid analysis or advanced imaging.

Treatment

Treatment depends on the cause. It may include rest, pain relief safe for cats, antibiotics, wound care, splints or surgery for fractures and dislocations, and long-term joint management for arthritis. Do not skip pain medication, because untreated pain slows healing. See signs of pain in cats.

Recovery at home

• Confine your cat, with low-sided litter and easy access to food and water. See senior cat home modifications.
• Limit jumping.
• Give medication as directed.
• Follow rechecks.

Prevention

• Keep cats indoors, to avoid cars and fights. See how to build a catio.
• Provide stable climbing furniture. See how to choose a cat tree.
• Block balconies and windows. See cat-proofing your home.
• Keep a healthy weight. See how to help an overweight cat lose weight.
• Trim claws regularly.

Arthritis and chronic limping

In older cats, limping is often subtle: a stiff gait, reluctance to jump, shorter leaps or less grooming. Owners often put it down to age, but arthritis is common and treatable. Weight control, joint-friendly diets and supplements, home changes and prescription pain medicine designed for cats can give a real improvement. See arthritis in cats and senior cat home modifications.

Young cats and growth problems

Kittens and young cats can limp from fractures, dislocations or growth disorders. Some breeds have inherited conditions such as kneecap luxation or hip dysplasia. If a young cat limps without injury, ask your vet about imaging. Early treatment can prevent lasting damage.

Claw and paw problems

A torn claw, an ingrown nail, a thorn or a cut between the toes can cause surprising pain. Check the paws gently, and look for bleeding, swelling or licking. Do not pull out deep objects. If the nail is bleeding, apply gentle pressure and call your vet. Keep claws trimmed to reduce snagging.

Tracking the limp

Note when the limp began, which leg it is, whether it changes during the day and whether it worsens after rest or exercise. A video of your cat walking helps your vet, since cats often walk normally in the clinic. Bring any photos of swelling or wounds.

When to see a vet

See a vet if your cat limps for more than a day, or at once if it is severe. Use the US vet directory to find a clinic.
