I like Showcase Cages. I have had good luck with them (have one for my ball python Shayna, one for my Bearded Dragon, one for my leopard geckos, and will be getting one for my corn snake when he is big enough). Closed on threes sides, but open glass sliding front. Vision Cages are similar, but I don't have any.

I like these type of "display cases" because they keep heat and humidity in and are easy to clean. Glass tanks are generally not good for keeping heat and humidity in. Of note, ball pythons are not great display animals though. They hide 95% of the time.

These types of tanks are expensive though (relative to a glass tank) and you would probably want to get one that Mitch can live in forever. So, if you get it soon, make sure there are many hiding places for him so he doesn't get overwhelmed and stop eating.

Also, at least with the Showcase Cages, there is a lip on the front top, just above the sliding doors, that a small snake could crawl into. When I put Shayna (my Albino Spider Ball) into it, she was about a year or so old and I pushed newspaper up into that hole (which runs the length of the enclosure) so she couldn't climb in. Now she is too big anyway at 2+ years and 1100G.

Depending on the size tank you get, I would recommend an undertank heater that runs the depth of the tank - Showcase has a indent for one - on one side. I would also use a red light (low wattage) for light so you can see him at night, but not for heat. If the tank is big enough (I have a 4FTX2FT deep Showcase Cage for Shayna), you might want to use a radiant heat panel as well. Shayna has a radiant heat panel on the back right side (keeping it about 87 degrees below it), a UTH on the left side (keeping it about 88-91 degrees on top), and it is about 80 in the middle of the tank and 77-80 at the front.

MAKE SURE TO USE A DIMMER SWITCH WITH THE UTH and a thermostat for the Radiant heat panel (one specifically designed for that - I use helix controls). I use a Home Depot lamp dimmer - $10 - and good to 300W. I have found reptile type dimmers not as effective or precise. They tend to get the UTH too hot even on the lowest settings.

I also use a reptifogger with a humidistat to keep the humidity 58-62% or so, with up to 70% when she is going to shed.

I hope this is helpful and good luck.
