Last night I decided to leave Archie loose around the house overnight. With it being windy, cold and drizzly I thought it would be a great night to try it as I knew he wouldn't want to go out. Steve got up once to check on him, he was on the mantle piece, I got up about 7am, and he was still asleep on the sofa. He had used his litter tray which I'd left in the utility room for him, yeah I think it went well.
