Why Is My Cat Limping or Holding Up a Paw? From Sprains to Blood Clots
๐จ Check first
Critical emergency red flag: If your cat suddenly lets out a piercing scream and collapses, with one or both hind legs limp and dragging, the hind paw pads ice-cold and bluish-white, and breathing fast, this is aortic thromboembolism (saddle thrombus): a blood clot formed in the heart that has lodged in the leg arteries. Every second counts, so rush to an emergency vet right away, even at night.
๐ The answer in 3 seconds
- If there is no scream or paralysis, and your cat is alert and eating but holds up a front or back paw while hopping, it is often a mild sprain or bruise from a bad landing, torn claws, ingrown claws, or a splinter in the paw pad.
- In outdoor or multi-cat households, a warm, swollen leg accompanied by lethargy and fever may point to an abscess from a bite wound.
- Do not pull on or manipulate your cat's leg at home, as this can worsen fractures or dislocations. Confine them to a crate or small room, limit jumping, take a video, and see a vet.
๐ Flowchart
- Step 1Emergency check first: Gently touch the paw pad of the dragging leg. If it is cold, pale, completely limp, and causes agonizing pain when touched, suspect a blood clot and rush to an emergency vet immediately.
- Step 2If the paw pad is warm and your cat is alert, look at (but do not handle) the underside of the paw and between the toes. Check if a claw is torn at the base, an ingrown claw is piercing the pad, or if there is glass or a plant thorn.
- Step 3To prevent your cat from jumping off cat trees or furniture and worsening the injury, keep them in a single-tier crate or a small room without jumps, take a smartphone video of their walk, and head to the vet.
โญ Step-by-step fix
Step 1 ยท What you can do at home right now
Emergency check first: Gently touch the paw pad of the dragging leg. If it is cold, pale, completely limp, and causes agonizing pain when touched, suspect a blood clot and rush to an emergency vet immediately.
Step 2
If the paw pad is warm and your cat is alert, look at (but do not handle) the underside of the paw and between the toes. Check if a claw is torn at the base, an ingrown claw is piercing the pad, or if there is glass or a plant thorn.
Step 3
To prevent your cat from jumping off cat trees or furniture and worsening the injury, keep them in a single-tier crate or a small room without jumps, take a smartphone video of their walk, and head to the vet.
โ Never do this
- Trying to find where it hurts by twisting, pulling, or tightly gripping your cat's ankle or joints (this can complete a hairline fracture or worsen ligament damage).
- Putting human pain-relief patches containing NSAIDs (such as indomethacin or loxoprofen) on your cat's leg (absorption through the skin or licking can cause acute kidney injury or severe gastrointestinal damage).
