I bought two of these litter boxes and I really love them. They seemed small at first. My biggest cat is about 22 lbs. But both of my cats don’t seem to have a problem with the size. I also like that the base is very deep so it holds a lot of litter and the plastic liner does get torn at all anymore. The dome holds any litter in neatly as well. They’re really cute and wish I’d gotten them sooner.
