Petmate Booda Dome Clean Step Litter Box

Brand: Petmate

A round enclosed box, roughly 22.5 inches across and 19 inches tall, moulded from 95 percent recycled plastic. The entrance sits on top of three steps whose ridges pull litter off the paws before the cat leaves, and a carbon filter in the roof handles smell. Interior volume is noticeably larger than a standard hooded pan, so a big cat can turn around without pressing against the walls.

A good fit for cats that scatter litter across the whole room and for homes where the box stands in a hallway. The dome shape eats floor space and does not tuck into a corner, unlike rectangular boxes. The lid clips can crack after a couple of years of daily removal, and shy cats sometimes dislike the single narrow entrance with no second exit.
