Cat Health Symptom Awareness

Why is my cat limping?

This can have many causes

Limping in cats can have many possible causes — from a soft-tissue injury to a more serious orthopaedic or neurological issue. Cats often hide pain, so a limp may indicate more discomfort than it appears. This page lists broad cause categories and the warning signs that should prompt veterinary contact. It is not a diagnosis or treatment guide, and it does not recommend pain medication.

Possible cause categories

Categories only — not a diagnosis. A veterinarian can identify the specific cause through examination and tests.

  • Soft-tissue injury (sprain, strain, bruise).
  • Bite wounds or abscesses — particularly common in outdoor cats and not always visible early.
  • Paw or nail injury, foreign object in the paw.
  • Trauma — falls, vehicle impact, fights.
  • Orthopaedic, neurological, or joint issues that need professional assessment.
  • Other chronic conditions a veterinarian can investigate.

Emergency signs — contact a vet immediately

Urgent

If any of the following are present, treat the situation as urgent and contact a licensed veterinarian or emergency clinic.

  • Inability to bear any weight on the limb
  • Obvious deformity, open wound, or visible bone
  • Severe pain — vocalising, hissing when touched, or hiding in distress
  • Suspected trauma (fall, vehicle impact, fight)
  • Sudden paralysis, dragging of a limb, or loss of use of both back legs
  • Significant swelling, heat, foul-smelling discharge, or rapidly developing wound
  • Limping with lethargy, fever-like behaviour, or refusal to eat

What you can safely observe and report

Observe

Notes that help a veterinarian make an informed assessment when you call or visit.

  • Which limb is affected, and when did the limp start?
  • Is the cat willing to bear any weight?
  • Are there visible injuries, swelling, scabs, or foreign objects?
  • Is the cat hiding more than usual or behaving differently?
  • Did anything happen — outdoor access, a fall, a fight, a chase?
  • Any other signs: appetite, energy, fever-like behaviour, breathing?

What not to do

  • Do not give human medications (including anti-nausea, anti-diarrhoea, or pain medications) unless a licensed veterinarian has specifically instructed you to. Several common human medications are dangerous to cats.
  • Do not try to diagnose based only on this page or any online content.
  • Do not delay contacting a veterinarian if poisoning is suspected, if your cat has collapsed, is having seizures, has trouble breathing, or is in severe pain.
  • Do not rely on calculators, guides, or AI tools for emergency decisions.
  • Do not ignore symptoms that worsen, persist, or pair with other concerning signs.
  • Do not give human pain medications. Paracetamol/acetaminophen is highly toxic to cats. Several other human medications are also dangerous.
  • Do not attempt to splint or bandage a limb at home except under veterinary guidance.
  • Do not assume an outdoor cat's limp will resolve on its own — bite wounds can develop into abscesses that need treatment.

When to contact a veterinarian

Contact a veterinarian or emergency clinic immediately if your cat cannot bear weight, has a visible injury or deformity, is in severe pain, or has experienced trauma — sudden loss of use of both back legs is a particular emergency in cats. Contact a veterinarian promptly if the limp persists, worsens, or is paired with other signs. Many causes of feline limping need physical examination to identify safely.

Why is my cat limping? — Frequently Asked Questions

Can I give my cat over-the-counter pain medicine?
No — and it is particularly important not to do this in cats. Paracetamol/acetaminophen is highly toxic to cats and can be fatal. Several other common human pain medications are also dangerous. Do not give any pain medication unless a licensed veterinarian has specifically prescribed it.
My cat had a fight and is now limping. Should I wait?
Bite wounds in cats — particularly from other animals — can develop into abscesses that need veterinary treatment. Even small puncture wounds can be significant. Contact a veterinarian rather than waiting to see whether the limp resolves.
What if my cat suddenly can't use their back legs?
Sudden loss of use of both back legs in a cat is a veterinary emergency. Do not wait. Contact an emergency clinic immediately.
