I read an interesting article today about hooded cat boxes.
It seems some cats who pee outside the box do not like their hooded litter box.
From the human perspective, these types of litter boxes can be desirable as they tend to keep the odor inside. But many cats find the smell undesirable ~ especially if the box is not cleaned often enough.
Removing the hood is one of the simplest solutions to try first for anyone having this problem.
