I live in a small apartment and was reluctant to get a cat because of the litter box. This one fits great in my bathroom and masked the smell.. at first. I scoop out the litter daily so I am not sure if the filter seems to be working or if you are supposed to do something to activate it..? There were no instructions provided so that part is unclear. I do love the drawer and hook for the scooper. Overall, satisfied and happy.
