It is possible for cats to recover from blood clots on their own, but cases are rare. Feline thrombosis is common in obese cats, cats with family inheritance, and cats that have undergone open surgery. The prevalence of feline thrombosis is not high, but the mortality rate is high. If a cat at home recovers from blood clots on its own, first of all, congratulations to the owner, and secondly, to prevent the cat from relapsing again.
