Cage Height?

[SnoopySnake]

I'm curios about what your guys' opinions are on enclosure height. I personally would like to be able to provide enclosures as tall as the snake is long (I know this isn't always possible with snakes like burms, retics, etc.). I also believe that what most of us consider suitable for a captive animal is usually not actually much height compared to what these animals face in their natural habitats.

For example.. it seems as if many people consider a 4x2x2 as a tall enclosure for a terrestrial snake, such as ball pythons and dumeril's boas, but if you think about it that's probably roughly the height variance that they would face in their natural environment.

Not trying to start a debate, I'm just curious about everyone's views on what we should be providing for enclosure height. I do realize this can depend on species.
