My cats like it, I think its because they don't have to clean the thing. I however am not impressed. My biggest problem with the box is the clasps. Once a liner is in place it was almost impossible to get it to clasp. The filter mine came with does not fit snug in the compartment and the door on top holding the filter does not stay closed.I do love the door. My cats always knock off the solid plastic ones but since this one is flexible they are able to to get in and out of the box and the door stays in place.In summation clasps bad, door good. Would not recommend this product, maybe Scott or Eddie would.
