I've been feeding two feral cats (used to be more) for the past few years, both in good shape and fit looking. This past summer one of them disappeared for about a month and then returned with his ear clipped and a few pounds heavier. Now he gained a lot of weight. He sits by front door looking for food 5 or 6 times a day (I was giving more than usual to put on some weight for the winter) I don't know whether or not I should cut back on his food, getting to heavy can't be good. I feed him both wet and dry food. Any suggestions or comments would be welcome
