Cats can survive thrombosis, but the chance of recurrence is high. The incidence rate of thrombosis in cats is 6%, but the mortality rate is indeed 100%. Generally, cats with thrombosis have no symptoms in the early stage. Once the disease occurs, it means that the body has been blocked. Some cats with good health can survive, but the hearts of well-treated cats are also fragile. Cat owners should be careful not to frighten the cats to avoid recurrence.
