idk, it probably helps them learn. I've only bitten my cat back twice, and hes super cautious about biting me that hes realized his mistake the moment the teeth touch and is instead running away
Looks like Mimi has Kirby tier succ seeing how she literally just inhales that cat food... I don't think Roy could ever prepare enough for when they finally do the deed, poor boy is going to be a dried husk at the end of it...
Actually most cat and dog food is relatively safe to eat. So if you're ever in a survival situation, remember that those can be used as emergency rations actually.
