My 9 month old male peaches currently weighs 12 pounds, I know it is because he eats, or tries to eat everything in site, I give him and my other 3 cats plenty of their own food and I try my best not to let him or the others eat people food but he is sneaky, he hangs around my feet when I am cooking something like steak then follows me to the table and tries his darndest to sneak a piece, he has a few times, and on the rare ocassions that I treat them to one piece each he will gobble down his then go eat the other cats pieces, I have to be there to shoo him away from the other cats pieces, even when I am done and put the plate in the sink he will jump up and lick the juice off the plate, is there something I can do to stop him from being such a pig?
