My somewhat newly acquired Rosy boa from the East Bay Vivarium at the HerpExpo in San Jose passed way sometime yesterday night while I was sleeping. She was having trouble shedding and I was going to soak her today and found her dead. She was always a little "lethargic" and I thought it was because she was just a more calm snake. Temps and humidity was spot on and there was a humid hide. She was feeding regularly and even passed urates and feces the night before.
