About an hour after I posted last night, I went upstairs to find that Pearl JUST had her pre-laying shed! Nest box is going in the moment I get home from work tonight! My sis in law is making it up right now, but due to Pearl's somewhat restless nature, I'm going to have to put it in her tub. (She's not really MEAN, she was just raised in a big facility where the snakes don't get much individual attention besides making sure they're healthy.)
