I bought this for my cat, thinking I could finally get her litter box out of my soaking tub.  However, when I thought she was going to o in my sister's cat came in & scared her, she refused to go in after that.  My cat then started using sister's litter box, so to get her back to her box I moved enclosure to sister's room & now both cats are happy as well as my sister.  It's working great for her since Bella loves to spread the pellets everywhere, so this keeps it in the enclosure.  Love the little drawers for litter & pads supply.
