My cat Frosty was sick and turned out he had a mass inside his mesentary and my vet had to do a bunch of stuff to see what it is, if it is cancer. Turned out they had to go in nonetheless and operate. He also got kidney failure on top of that. He was in the hospital for 2 weeks and the bill came out to almost $9K. If not for Healthy Paws, I might have been in a serious financial problem.
