My cat developed a hematoma so we took her to the vet and they charged us $400 to drain it without anesthesia. After about 2 weeks it filled back up again so we took her to a different vet and they want us to spend $1,000 to have it surgically drained but with no guarantee that it won’t come back. Will it heal on its own or is it worth it to spend the $1,000 with the chance that it might come back?
