The top entry style is genius. My cat loves the privacy and it’s way less messy than traditional litter boxes. The style is really cute and it looks good in any room. My dog isn’t interested in it so that’s solved our problem of him taking treats away from my kitty. The cat wipes her paws in the grates and the litter falls back into the box. So easy to clean. Spacious enough that my cat loves it. She took to it immediately and just jumped right in. I would highly recommend this litter box over any other litter box on the market today.
