Cats are good at hiding pain. A cat that starts limping, stops jumping, or refuses to use a leg may have an injured claw or pad, a bite wound, a sprain, or a more serious orthopedic or neurologic condition. It is tempting to watch for a day, but the severity and circumstances should guide that decision.
What to note first
Is the cat putting any weight on the leg? Was there a fall, fight, or outdoor excursion? Does a paw look swollen or is a nail missing? Is your cat eating and moving normally otherwise? Puncture wounds from bites can be small and difficult to see even when infection is developing beneath the skin.
Emergency signs
Go to an emergency veterinarian if your cat cannot stand or walk, has a visibly deformed limb, experienced significant trauma, or appears to be in extreme pain. Sudden loss of use of one or both hind legs—especially with cold paws or distress—is an emergency because impaired blood flow is one possible cause.
Safe care while arranging an exam
Keep your cat indoors in a quiet area, limit jumping, and place food, water, and a litter box within easy reach. Check the paw only if the cat tolerates it. Do not pull at a painful limb, apply a tight bandage, or give human pain medicines; acetaminophen is especially dangerous for cats.
How the veterinarian finds the cause
A hands-on examination may identify painful joints, abnormal reflexes, a wound, or an abscess. X-rays or other tests may be needed. Because cats may conceal discomfort, improvement in their willingness to move does not necessarily mean the underlying injury has healed.
Can a video visit be enough?
A short video of the gait can be helpful for triage, but it cannot safely rule out a fracture, assess circulation, or treat a painful bite wound. Persistent lameness deserves in-person assessment even when a cat still eats.
