I have 2 cats. 1 will eat dry kibble and cat treats only, will eat some wet cat food but not most, he is the most particular eater i have ever seen for a cat, which is especially strange because when we adopted(by adopted i mean took home from tow yard i worked at) him he was starving to death, like you could see his ribs his face was sunken in and he was about 5-6lbs underweight. someone had obviously left there indoor cat outside and abandoned him and he was struggling to survive, likely would not have made it another few weeks when we took him in. That was 8 years ago he is doing great now.
My other cat will eat damn near anything, ive seen her eat any and all meats in any form(raw, cooked, jerky, salami, pepperoni, sausages) particularly bacon is probably her favorite, she eats cheese, likes beer and whiskey, eats some flavors of chips, pasta, loves the cheese sauce from mac and cheese if i eat a pot of M&C and put it on the floor after she will eat any leftover pasta and lick the pot clean. seen her eat rice and beans as well. Not bread though.
