Besides the stereotypical tuna obsession, my cat likes lasagna, pad thai, boiled chicken, and McDonald's french fries (only McDonald's, mind you, and they have to be fresh piping hot). They have to be in bite-sized pieces, though, because he's a spoiled house cat and apparently doesn't know how to use his teeth. I wouldn't actually have known about the pad thai except I had a friend over who dropped some on the ground and he gobbled it right up before she had a chance to pick it up. He's also shown interest in fried rice and Red Lobster Cheddar Bay biscuits though I didn't allow him to actually eat any. Based off the food items, I think it's largely due to the butter/oil/grease that he smells. He's never shown any interest in other seafood besides tuna, strangely enough.
