My cat will ignore wet food and meat if there are carrots around. Carrots are obviously not as unhealthy as donuts (to humans at least, I gotta assume that’s true for cats too), but they’re still not something I would expect cats to go for.

We don't feed our cats donuts, but I have no doubt in my mind they would recognize it as food and go for it, if they really wanted to. (With our current cats, we've never had an issue, but we had one before that would go after any food you left out. And he was super thin, just very food-driven.)

But yeah they're feeding that cat junk food.

Ive known multiple cats that would eat waffles. One of them even stole one off the kitchen counter
