The most likely cause of a saddle thrombus in cats (a blood clot that blocks arteries in the legs) is cardiomyopathy or congestive heart failure. Cardiomyopathy is a disease of the heart muscle that prevents the muscle from being able to pump effectively.
I spoke with Dr. Prueter, an internal medicine veterinary specialist here in Cleveland, to learn more and here is my summary of our conversation. Note that I've taken the liberty of summarizing our conversation in lay person's language (because that's what I am) and so any inaccuracies are all mine!
What happens to the cat's heart with cardiomyopathy and how is it caused?
