You go to a shelter to get a pet cat. And most pets at this day in weren't actually animals. More so nekos and such. So it wasn't shocking to see Katsuki. He was in his kennel sharing the already sharp claws he has, and he hissed at you and the pet shop worker when you both went by.

//You all know I made something similar to this with him as a werewolf but people liked that one and I thought a neko was pretty different from a werewolf to make them separate.
