I'm getting a 6 year old normal female BP (my first snake) from a former coworker in a month or 2 (she's in no hurry to get rid of it) and I'm looking at the Animal Plastics cages after someone recommended them to me here and I have a few questions.

1. I'm considering the T8 because I've read a couple places that people get the divider and house 2 snakes in it, and I would love to get a pretty morph some day so I'm just wondering if the girl I'm getting now will be okay in just half of that cage? I'm not sure how big she is.

2. Heating. I have ton of questions here. As far as UTH goes, I see a lot of people recommending heat tape but I'll be honest, I am a little intimidated by the stuff. The idea of just being able to plug in a heat pad is a lot more familiar to me but will it work as well on this type of cage? And as far as ambient temps go, I like to keep my house cold so I know I'm probably going to need something other than a UTH to keep the cage warm. I have an extra clamp lamp lying around that I was hoping to put to use for that but it doesn't look like these cages come with holes in the top for that. Are the "8" circle screens" in the add-ons what I need?

3. And just how massive are these things? I mean I obviously have the dimensions but I'm trying to find space for a cage this large in my tiny bedroom that already houses 6 fish tanks, a hamster, and a Great Dane.
