Suitable for medium to small cats. "This litter box is suitable for pets weighing between 3.5 lb and 15 lb." My girl cat in the picture liked it and used it, but my boy cat who's bigger used it sometimes, but it was too small for him. I only used it for a couple weeks then cleaned it out to sell. Makes life way easier! I have the bags that go with it. You can remove the top lid to empty the used litter and add more in the main box as you go. Works great!
