Well, it took more than 24 hours, but he finally moved! Not much, but he apparently came out of the crate & picked at the food a bit. Cotton now lets me touch him with a long pet toy without reacting. I think he's just gone more into his shell. Poor thing, his world has been turned upside down and he doesn't know what to do yet. Wait 'til he has to go to the vet. Since he has lived outside for most of two years, he'll need to be tested before I even think about introducing him to my girls.
Anyway, here's a picture. You can see he's not a happy camper.
