Well Buddy finally gave it up and it's been sent off to the lab. I'll find out the results tomorow. I returned the bags of Feline Pine and exchanged it for a non-scented scoopable litter. I also put a bigger cat box in the bathroom for him. He's already used it. Now all the boxes have scoopable litter in them. Everyone seems content. They've had their canned treat for the night and everyone is out like a light. Buddy is in my bedroom window enjoying the fresh air and the peace and quiet. Maybe this is solution. I tossed out the kitty tent that was peed on. Don't want to take any chances.
