HI, I just joined this thing. I have a 2 year old rat with a mammary tumor i want to get it removed but my vet is trying to charge me $350!! Is this reasonable? I've already paid $60 just for the initial visit. I live in New York...does anyone know a reasonably priced vet? How much should I expect to have to pay? Her tumor is getting bigger and bigger and I want to help her asap!!!
