The culprit, as I posted in another thread, was Doogie!! I figured I'd try switching back to the scoopable litter that I used before. Never had any problems.

I had cleaned and filled a box with the new stuff and put it in the room. As I went back in there to put the lid on, there he was with a pile of poo on the floor, making the motions of trying to cover it up. I guess he was impatient and couldn't WAIT till the box was filled.

Now since I've changed them back to scoopable (I left 2 with Feline Pine till it's time to dump it) everything has been fine. I even keep going in there to check.

I'm just greatful it wasn't a behavioral problem.
