Why Is My Cat Limping? Causes, When to Worry, and What to Do

Cats are masters at hiding pain — which is why noticing your cat limping can be genuinely alarming. It means your cat's discomfort has exceeded their ability to mask it. Understanding why cats limp and what to do about it depends heavily on the severity, the limb affected, and the accompanying symptoms.

Common Causes of Cat Limping

Injury and Trauma

The most common cause of sudden limping in cats is physical injury:

• Sprains and strains — soft tissue injuries from jumping, falling, or wrestling with other pets
• Fractures — broken bones from falls, car accidents, or severe trauma
• Paw pad injuries — cuts, puncture wounds, splinters, or foreign bodies lodged in the paw
• Nail injuries — torn, broken, or overgrown nails that catch on carpets or surfaces
• Bite wounds — especially in outdoor cats; cat bite abscesses frequently develop in the legs

Arthritis

Osteoarthritis is very common in middle-aged and senior cats — far more common than most owners realize, since cats rarely vocalize joint pain. A cat with arthritis may limp, move more stiffly, have difficulty jumping, or avoid stairs.

Abscess

Outdoor cats frequently sustain bite wounds from other cats that initially seem minor but develop into abscesses — pockets of infection beneath the skin. These cause significant swelling, warmth, pain, and sometimes fever. A limping outdoor cat who has been in recent contact with other cats should be checked for puncture wounds.

Cardiovascular Disease (Aortic Thromboembolism)

Feline aortic thromboembolism (FATE) is a serious cardiac emergency where a blood clot blocks blood flow to the hind legs. This causes sudden, severe hind limb paralysis or extreme weakness — often both legs simultaneously — with cold, pale paw pads and extreme pain. This is a life-threatening emergency.

Neurological Conditions

Spinal cord issues, intervertebral disc disease, and other neurological problems can cause limping, weakness, or incoordination. This is more common in senior cats.

Infections

Bacterial or fungal infections affecting bones (osteomyelitis) or joints (septic arthritis) can cause significant limping and require systemic treatment.

Signs That Mean Go to the Vet NOW

Treat cat limping as an emergency if:

• The leg hangs at an abnormal angle or appears broken
• Your cat won't bear any weight on the limb at all
• There is an open wound or visible bone
• Both hind legs are suddenly weak or paralyzed (possible FATE — call emergency vet immediately)
• Your cat is in obvious, severe pain (crying, hissing when touched, unable to move)
• There is significant swelling, heat, or abscess at the site
• Bleeding that won't stop

When to Wait and Watch (Briefly)

If your cat is putting some weight on the leg, the limping is mild, and there's no visible wound or severe distress, you can monitor for 12–24 hours:

• Confine your cat to a safe indoor space to prevent worsening injury
• Check the paw carefully for foreign objects, cuts, or swelling
• Do not give human pain medications — acetaminophen and ibuprofen are toxic to cats
• If limping hasn't improved in 24 hours, or worsens at any point, contact your vet

Frequently Asked Questions

Why is my cat limping but not crying or showing pain? Cats are hardwired to hide pain — it's an evolutionary survival mechanism. A cat who is limping is almost certainly in discomfort even if they don't vocalize it. The absence of crying, hissing, or obvious distress does not mean the problem is minor. Any limp that persists for more than 12–24 hours deserves veterinary evaluation.

My indoor cat is limping — how did they get injured? Indoor cats injure themselves more often than owners expect. Jumping from heights, getting a paw caught under furniture, wrestling with toys or other pets, or simply landing awkwardly are all common causes. Indoor cats can also develop arthritis, infections, and other medical causes of limping that have nothing to do with trauma.

Can arthritis in cats be treated? Yes — feline arthritis is underdiagnosed but very treatable. A 2022 FDA-approved injectable medication (frunevetmab/Solensia) specifically targets the pain pathway involved in feline osteoarthritis and has shown significant results. Other options include environmental modifications (ramps, lower litter boxes, heated beds), weight management, and certain supplements. Ask your vet about options.
