Cats are VERY particular about thair potties and you made several changes all at once! Changed the box, changed the place, changed the litter and iner (fresh / new ones). WHOA, slow down, hoomom! TOO MUCH CHANGE to the potty!!!!

Return everything to as it was (OK, you don't have to put the 'old'litter back) and don't even THINK about disturbing it for a few weeks. Ozzie doesn't even TRUST you anymore, he doesn't know WHAT you silly hoomom want!!! Let everyone get settled and back to normal. If you want to make a change, do ONE thing and see how that goes, for several weeks. Then try again.

You have 2 cats, you must have at least 2 boxes out.
