Thanks for the info, I have always fed my two siamese a little bit of wet food as a treat and they LOVE it. I think they actually prefer it over dry food, I just didn't think it was healthy for them to have all the time. Our foster kitty just loves food, and any wet food he has had he scarfs down. It is my boyfriends two cats that I think are going to have the most trouble, when we give them some they pick at it a bit but never finish (to the delight of the other cats!)
Eddison is probably not hugely overweight, he is a large cat and very tall. But he does have a large belly, and rolls
He is still very active, and I'm worried if he gains any more he will not exercise as much and he may become obese. He has gained 2 lbs in approximately 3 months with us.
