we have a cat that used to be indoors. She now lives outside due to the fact that she pees/poops anywhere inside....regardless of how clean her litterbox is. she's healthy too. We went to the inlaws this past weekend and when we came back Sunday evening in the process of bringing stuff in from the van the cat got in the house. She was in maybe 15 minutes. The door was open most of that time so she could've gotten out if she wanted. When I got ready to go to bed that night I smelled it. Cat mess. Looked and couldn't find it. so last night it was kinda chilly and I pulled out extra blanket out of the closet floor. Found it! That blasted cat in those few minutes she was inside went in there and peed on it. I think I'm going to open the door and stand there with a water gun to teach her NOT to come in anymore. So now on top of the mountain of laundry I have to wash this blanket. I used to love cats like crazy but this one has made me think that they are not all they're cracked up to be.
