"Catatouille" is an episode of The Itchy & Scratchy Show.
Itchy is controlling the mind of Scratchy, a chef in a restaurant frequented by cats. Itchy makes Scratchy use a knife to cut out his intestines and fry them, then makes him remove his eyeballs to stir them and roll them into the drinking glasses, and then to spray nitrogen on them. Scratchy (under Itchy's control) puts the cooked intestines and the eyeballs on a dish (It is revealed that Itchy did what he did to Scratchy with other cat chefs). The dishes of cat organs are served to the cat customers. Not long after the cats begin to eat, Itchy then holds up a sign that reads "You're eating cat." The cats all vomit, causing a massive buildup of vomit in which they drown.
