Nothing if your cats don't mind them. But some cats don't like them and
may avoid the box if present. The cat may dislike being unable to
position itself a certain way or feel confined by the hooded box.

That's very interesting. I always thought that the hood was to prevent the
cat from scattering the litter in every direction around the box. The hood
seemed like a human convenience, and I never gave any thought to how the cat
might react.

My thanks to you and Gail. I'll remember this.
