Please help! I have an 8 year old female cat named Stella who had surgery in November to remove a calcium oxalate bladder stone. I was told by my vet she would have to eat prescription food for the rest of her life. She has been eating about 3/4 of a can of Science Diet C/D wet food plus 1/4 cup of the C/D dry food daily. The vet tech warned me that she might gain some weight and to "watch out". Well, Stella has gained about 1.5 pounds in 2 months! My vet has offered no help as he insists she must stay on this food. Has anyone else encountered this situation? I don't want her to get another bladder stone, but I also don't want her to become diabetic due to excess weight and carb intake. Any suggestions would be greatly appreciated!
