I swear, I only left the room for a minute! I just happened to hear him drag something out of his crate and across the kitchen floor. It's been so warm today that I left the back door open so they can come in and out as they please, so I followed the trail to see his latest handiwork.
I'll take this as a sign that he wants a new bed… or maybe he just thought it would make a really good toy at that moment. Ah well, it's about time for a new bed anyway, I suppose.
