Thank you, everyone, for your concern about Thumper. I was beating myself up, crying, wondering if he would disappear and what I would do, etc. and it seems he was having a whale of a good time. I had slept very little on Friday night and planned to drop into bed early on Saturday, so by 12:30am I'm practically asleep on my feet when I went downstairs to check for what has to be the last time. There he is, at the glass door, not banging on it, not crying, looking as though he does this every day. When I huigged him, practically smothering him I must admit, his attitude was very "Hey, mum, gerroff. Where's the food?" He'll be shut in a bedroom in future when I have to go out onto the deck, and Luke in the bathroom or maybe Pete since Luke bites.
