My little chonk monster is actually pretty good with food, and isn't interested in human food much at all, possibly because he had to fend for himself for a few months before he imposed himself on me. He's certainly partial to the odd pigeon which are too slow/stupid to get away.

He currently has mostly dry kibble and water, but with the odd wet pouch for some variety.

I've tried him on a little milk before and he wasn't bothered, but I have semi-skimmed lacto-free, so I don't know if it offends his taste-buds or not.
