"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 his intestines and fry them, remove his eyeballs to stir them and roll them into the cups, put nitrogen on them and put the cooked intestines and the eyeballs on the dish (Itchy does the same with other chef cats before Scratchy). Itchy sends the cats in the restaurant the dish, which they eat. Itchy then holds up a sign that says "You're eating cat." The cats all throw up, causing a massive buildup of vomit, in which they drown.and the episode ends
