3ft wire rack from Target holds a 3ft Neodesha Plastics standard cage perfectly (I used a piece of MDF over the wire shelf, and I painted the MDF to match the cage color). Below (and hard to see because it is clear) is a National Geographic 30x12x12 cage I found at Petsmart, great cage!

I have been using infrared heaters of late to see how my cornsnakes do. I moved these snakes out of racks and into cages to give them more room and hopefully more temperature options to see what they do. The temperature gradients are nice and gradual. I do like seeing the snakes come out of their hides at times to bask for a time, then retreat back under cover.
