Apparently nowadays they make claw caps that allow them to retract? You can look into it, but if you're on top of claw clipping he won't be able to scratch even if he tries :) make sure to start playing with his claws and feet to get him used to handling for nail trims

Also get him neutered before 4-5 months because neutered male cats produce less of the allergen! Feel free to reach out with qs I volunteer at a cat rescue so all I do is take care of kittens lol

Don't do the claw caps because it forces them to keep their claws out, feed him Purina liveclear and keep him out of rooms you don't want him in. My household of allergic friends took in a stray cat and does those + air purifiers in rooms and they have no issues

To save you some time you might want to wait on that shiny hunt specifically, one of the first side quests you get gives you a guaranteed shiny mareep so unless you want two of them haha

I thought those were potatoes and didn't question it

Girl, I am losing my mind
