Last night, all my best laid plans went completely to hell. My goal was to lure Thatch out after I was in bed, use Annabelle to track him, and get him into a carrier. I pulled out Annabelle's carrier, so she could play in it since I want her to be comfortable with it for her first trip to the vet. I also prepared Thatch's carrier, so that I could just pop him into it when I caught him.
Annabelle was sleeping in her carrier when I turned off the lights at 9:30. I slept soundly until 2:45, when he and Annabelle got into it. He ran back to his original bookshelf, so that was a dud.
