Hi I am currently thinking about getting a rack set up for my snake. Funny enough I only have one snake, but for future ball pythons. I notice more people use racks over a display cage for their ball pythons.

Few Questions:

What is a great reliable website I can purchase a good rack?
What is the best heat source?
What thermostat do you recommend?
What is a good size for adult ball pythons?
How safe are racks and do I need to be worried about escape, and if so how to prevent it from happening?
