Help! E. Black Rat Urgent Care!

[Bubonic]

Hello Everyone,

Ty in advance for any and all advice. I am momma to Bubonic, my Eastern Black Rat Snake. Just got him, he's a juvie, and he's in a horrific cage (roughly 36x16x10 tupperware container).

I've been looking all over at care sheets but having trouble picking out which to follow (even when weeding out those that (basically) promo diff things). Any ideas for care or a caresheet?

I want something as close to a natural habitat as poss for him, so he's happy as can be and can grow up big and strong like all the other Rat Snakes. (As any mother would want. :P LOL!)

Here's what I've learned so far (about Ratters in general):

NATURAL HABITAT:
-Deciduous forest surrounded by grass is ideal or
-Forests, grasslands.

NEEDS:
-To be arboreal.
-To swim ? (They're excellent swimmers.)

FEEDING:
-Small rodents.
-Also frogs, lizards, birds and bird eggs.
-Juveniles more likely to eat cold-blooded prey, while adults stick to warm nearly all the time.
-Some species of ratters are called "chicken snakes" b/c they love to eat chicken eggs.
-They love to ambush and to actively forage.
-After killing, sometimes they continue hunting. Might kill more and return to original prey.

I also learned that their lifespan is unknown! Cool!

So for starters, I'm thinking they need a tall cage, and b/c they love to forage, a wide one as well. Probably as big as I can make it? Wide, tall and deep equally would be perfect ?
