SAS,

I went and bought the scoopable litter I used before I switched for FP.

The culprit is Doogie!!! Before I could even get the first box's lid on filled with the scoopable, I walked in the room and there he was with a big pile of poo, making the motion like he was trying to cover it.

At least I now know who it is. Let's hope this litter will do the trick. I have one box for each cat, so that isn't the problem.

I'm keeping my fingers crossed (as I slug down a glass of wine).
