I needed this litter box for my growing Maine Coon. She is a scratcher and the previous open box was just too messy. She pawed everything to cover her deposit...except the litter. I researched on line and in stores for a box that had high sides, was enclosed (nix the flap door immediately), easy to clean, odorized, and had a handle. This CP7 was the winner. She uses it so much I thought she was sick or something but realized she just enjoys having her own space to paw and scratch and throw litter all around ‘to her heart’s content.’ So much so that I ordered an second CP7 for my smaller Tuxedo cat. This way the Tuxedo will not have to wait for Ms. Maine Coon to exit the litter box. One for each. Easy to clean and odorized. Large inside capacity is purrfect (17 inches). It is a mild hop to get into the box but what cat does not like a short jumping challenge? Comes as a top with handle and odor filter and cheesy locks and a bottom pan. The locks are a bother but I use them just to secure the top as a precaution to rambunctuous cats. I lock just one or two then have to remember I locked them as I try to lift the top off to clean the box. One other thing making this an easy litter box to clean is my purchase of the Litter Locker II. That litter keeper is a Godsend and so much fun and EASY to use. Research it and see what you think. Do not know if WalMart carries it. I got it at a garage sale and am one happy cat owner.
