Go now — this is painful
Saddle thrombus
A clot from the heart lodges where the aorta splits to the back legs.
Do now
- Minimize handling. Pain is severe.
- Feel the paws only once — cold and pale supports the suspicion.
- Call emergency: “sudden hind-leg paralysis.”
On the way
- Keep the cat warm and still. No massage of the legs.
Never
- Do not delay because the cat can still sit up.
At the hospital
Pain control, heart assessment, and a frank talk about options. This is a hospital decision, not a home one.
Hidden heart disease throws a clot. The cat may howl, drag both hind legs, and the paws go cold. Informational guidance only.
