Some Pokemon (like Shedinja and Cosmoem) don't eat at all, but still act annoyed if you drop the food on the floor.
Torracat has a new happy jump animation in USUM, so it's positioned further away from the camera than in SM so you can see it.
When Stakataka is on the Refresh screen, it tucks its entire body in, so there's no visual feedback when you pet it. You have to listen to the petting noise to know if you're petting the right spot.
