A woman points a gun at a man and he tells her she won't pull the trigger. We cut away, hear a gun shot, then return to them, only to see them kissing.
Linguini kisses Colette without consent, and she goes to pepper spray him but she goes along with the kiss. It's not particularly good but it could be worse?
Mention only: Linguini has a vision where he asks the food critic Anton Ego what he would like to order, and Ego responds "I'd like your heart roasted on a spit".
It's not technically possession, but the main human character is physically controlled just like a puppet by the main rat character for most of the movie.
Mild scenes showing characters spitting out food/drinks (including some comical spit-takes), as well as a mention that a character spits out food that he doesn't like.
There's a scene early on mentioning that Gusteau's restaurant got a negative review, causing the brokenhearted chef to die shortly afterwards. It is possible that this refers to suicide, but it's not explicitly stated and we don't see his death onscreen.
A small comment is made about how a character is "thin for someone who likes food". Remy's brother is also significantly overweight and has a great interest in food, but there's nothing too bad that happens.
In the moped chase scene, there are multiple incidents of squealing tires and honking horns. Also when the pancake pan goes out the window there are squealing tires before the crash sounds.
