Ask Dr. Diehl: Cat Clots Paralyse Rear Legs

PODCAST (11:26) — If your cat suddenly loses control of its hind legs and is in severe pain, get her to the vet immediately. It’s probably Feline Aortic Thromboembolism.

That’s the advice from Morris Animal Foundation veterinary internist Dr. Kelly Diehl, who says a blood clot and heart disease may be responsible.

On the 3/22/20 KSCO Pet Radio, we discussed how a clot can lodge itself at the end of the aorta, where the blood flow to the legs “y”s off. Lost of circulation reduces or stops movement and, if not promptly corrected, can result in the feline’s death.

Here is a link to a Feline Aortic Thromboembolism page with illustrations and lots of additional information about diagnosis and treatment.

Sadly, my experience with this symptom was with my beloved bottle-baby, Larry, who lost hind leg movement after a fight with cancer and had to be painlessly euthanized. He was 16 at the time.
