He will be a year old sometime in the month of June....But he weighs 15 lbs even!!!! He got his leukemia shot this afternoon, and Fluffy got her stitches out..she only weighs a 6 lbs even....I thought he was heavy, but goodness..the vet said he is just a BIG kitty..he isn't fat at all......and he is very active, but it is usually in the middle of the night...She also told me I could put both of them on adult food now...They have been eating Authority kitten food and I wasn't gonna stop giving it to them until Fluffy was a year old....anyone recomend a good adult food for them?
