Cage or tank for pet snake?

If you're going to use a cage for your snake, be careful in picking one out. My dad used to keep a snake in a cage, the kind that has wire spaced closely together, and the snake was worming away at a small hole everyday until it was large enough to slither through. He got his head through fine but somewhere along his body he got caught and the wires cut him up pretty bad. My dad had to cut the cage apart to get him out.
