Pooping and Peeing Outside of Box
We got a Litter Round-up about 2 months ago and both cats used it with no problems until about a week ago. All of a sudden Penelope has stopped using it and has pooed and peed outside of the box at least two times each. I set up the old box again, thinking that maybe she was spooked by the Round-up somehow, but I'm not sure if that's the problem. Anybody have any other suggestions?
