Take him and put his paws in the litter so he knows it's the potty box. I'd leave the hood on the box.

Keep an eye on things. If your little guy has been using the litter box ok up until now it may be just the change in boxes. If he continues to pee outside the box or other places have him check out by your vet, it could be sign of urinary tract infection. Butterscotch urinated outside our bedroom door (very unlike him) that's what it ended up being. Antibotic and he was fine.
