Yes,these are great. I have 2 of these for my cats and my oldest cat will be 14 years old soon. The only problem I see with them is if you have cats that like to dig. Some times mine dig so much that a lot of the litter goes flying out the entrance. They will also some times pee with there back ends towards the entrance. This is why I have them on mats with puppy pee pads on top.
