Can cats get jealous of what other animals in the household eat? Bruce eats dry food. 1. because it is less disgusting in the litter box and 2. because it is sooooo much cheaper to do so and he shares his food with Minnie and Midnight outside. When we have tuna, I save him a bit in the cans and he has a "treat" which he loves. Only problem with that has been........he now thinks every can that is opened in the house contains tuna. This was comical up until I started letting Molly have canned now and then and now that Maggie is using can so she'll eat the puppy chow. He got miffed when seeing that the puppy got what came out of the can. He got even more miffed when I wouldn't let him eat it. He hasn't eaten his own food in 4 days. ugh Tonight I gave in and let him have a can of tuna. (I know, I probably shouldn't have but his allergies are full blown right now and he's not feeling too hot) I figured if nothing else I'd know if it was his appetite or not. Well, he's eating that tuna just fine. Obviously appetite was not the issue. Stupid cat.
