Looks good. I would cover the sides to make him feel more secure. Also i would leave the mirror on top. You would be surprised how strong a snake can push lol. Caesar pushed the corner up on a locking lid tub and got out as a 3 foot baby. Luckily i found him about 5 feet away curled up sleeping under a swivel chair.
Thank you! I'll stop by Hobby Lobby and get some black cardstock to cover the sides with. And woah! A locking lid! I'll leave the mirror on I'm glad you found him!
