bookcase cages

I built this cage from a cheep walmart bookcase. It came with a cardboard back, so I replaced that with 1/4" plywood. I put two locks on each door.(took a while to find a hardware store with eight locks keyed alike) I could have used the hook and eye screw lock, but housing venomous that wasnt an option. I wired lights for heat and ran them each to there own dimmer switch to regulate the heat. My biggest concern was the snakes getting on the lights, but it hasnt happened yet and its been full of snakes for 3 months. I have around $150 into the cage. Not to bad I thought for something so attractive. I have 2 more pics posted showing closer and different angles.
