Automatic Litterbox Central

The wings are extensions that snap onto the sides of the base to cover the drop holes in the globe so that any litter that your cat kicks through them will fall into the tray instead of on your carpet or floor. Some cats were even managing to pee out of the globe through the drop holes and that made the wings a very important feature.

They used to be a separate option but thankfully all Litter Robots come with them now.
