We received Dash a 50 lb. Sulcata a few weeks ago and noticed almost immediately what we felt were depression/stress issues. He received daily interaction with his previous owners and pretty much lived inside. We are now giving him a more natural environment with an outdoor enclosure and regular visits from us. We make it a point to interact with him as much as possible with activities such as reading a book to him. We stay in his pen for 5-10 minutes every time we feed and talk to him and stroke his shell. Despite all of this he is reluctant to come out of the house and walk around during the day. Any tips or tricks to help he get comfortable would be greatly appreciated.
