My 4 year old cat just had a saddle thrombus a few weeks ago. We took him to the emergency vet and they said we needed to put him down because it's a death sentence. His lungs were filling up with fluid and his lower legs were paralyzed. It was horrible.
After the fact, I was researching his condition and nattokinase came up. It has saved a lot of cats. I wish I has known about this before.
Looks like a good drug to stock up on!
