Our cat loves lunch meat, especially roast beef and then turkey and ham. But it is the good stuff and not the cheap stuff since I bought the small bags and he walked away so I gave it to the other feral cats outside.
My son Nick gives him goldfish crackers and he has had a piece of cheeseburger from BK a few times. Otherwise it is dry food and a variety of it, like kitten chow, whiskas, kibbles n bitts, meow mix, etc.
