I am working on designing a 'different' type of enclosure for ball pythons. I have ideas on a design, but I want to make sure I cover all bases...so I was looking for input from everyone.

What are the qualities of an enclosure that make them great for ball pythons?
What are the qualities of an enclosure that make them great for people to use?

If there is something about a current enclosure that you can't stand, what is it?

I want to create a 'Enclosure Checklist' of things needed to make the ball python and the keeper 'happy' with an enclosure. Something that is completely independant of the usual 'enclosure type' discussions....no tanks are bad, tubs are better here.....let me know the issues that make things better for us and the animals.

Help me out
