Here's some pics of my snow corn snake's setup. Not really that fancy, though.
The warm Side
The cool Side
The whole Cage
Digital Thermometer
Humidity Gauge
The top of the cage. There are some security clips or whatever they're called at the moment. I think I don't need a lock now since my corn is still a little small.
I've got a heat pad underneath hooked up to a dimmer (I had to get one over the internet since I couldn't find one at my local Home Depot) and some paper towel taped to the back outside of the cage to make him feel more secure. And I got a digital thermometer and a humidity gauge, so I can't get in trouble for not having proper epuipment.
