One mess in the litter box, one on the carpet. What was different from Night 2? First, we didn't play for a half an hour before I locked her in. Second, Carl did the honors since I went to bed earlier than I thought Sassy should be locked up. Did that make a difference? Was she angry with me? Not a clue. I thoroughly cleaned the spot where she pooped, sprayed it with a cat-away product and placed a box on top of it. We'll try another night tonight and if the same thing happens, it's down to the linoleum floor in the laundry room. It's about 1/5th the size of my craft room - just room enough for her box, a small blanket and food and water and no window. In the meantime, she's helping me craft.
