Randi,

It WAS the litter. I have 8 cat boxes. I put the clumping litter in 6 or the 8 and left FP in 2 of them. So far no more accidents. Everyone seems happy.

As far my back...too late. My lower back is hurting. I made a wrong move and twisted it. Oh well, I'll just soak in the tub and take some Motrin.

I vacuumed the whole room and scrubbed the area where the poo was with Woolite Pet Stain again, just to be on the safe side. I'm going to get another bag of scoopable and do the other two boxes and that'll be the end of that.

I'm glad I found out who it was. It was not know that was driving me crazy.

Thanks for your input everyone! You're the best!!
