That cage looks like you could make it work. From the looks of the snake its young and should not be able to reach the che but soon that will not be the case. You can make the cage work but you will need to get a screen cage to place around the che and the bulb. A simple brush of the che will cause a bad burn, they really cook.

The only other suggestion I would make it to get another hide so you have one on each side. Also the pcv pipe is not ideal. You really want something that has only one small door. For the time being I would push the pipe against the cage wall to make it a tad more secure feeling for the snake.

Im not sure how the snake would like laying in a tube like that but it you wanted to continue it use you could also get two caps for that pipe and cut a hole in one of them. That would make is super dark and secure feeling for your snake.
