Hey guys, I hope this problem hasn't been brought up too many times... didn't have the power to make a deep search before posting this We got our cat a closed litter box with a door a few months back. He is 1.5 years old, used an open litter box his first year. When we got him the closed one, he used to look at it like it's a space shuttle or something. Totally scared of the door... so we removed it for a while so he can get used to this whole walls and roof idea. He did get used to it, but when we put the door back he kept ignoring it. We tried all sorts of tricks like putting something between the box and the door so it would be half open - he used to buy it and get in, but when it closed behind him, he jumped outside and looked at us like it was all a conspiracy to trap him or something. We gave it some time, thought he eventually would have to use it and go in... but he preferred peeing on stacked piles of clothes rather then using that door. What else can we do to make him use it? We've been keeping the door unattached for a couple of months, but it kinda looses the effect of a closed box... since it's still smelly around it, and he drags the sand with him outside.
