Hello everyone, new here and to balls (but not to snakes and other reptiles).

I picked up a super sweet tempered, beautiful, very very skinny ball last night. I need some affirmation that I'm doing everything I can to turn this around and bring her back up to appropriate weight. I probably shouldn't have gotten this snake, but I fell hard for her... She was calling to me and I just couldn't bring myself to leave her. So here we are. The pet store had her in an absolutely abysmal set up, which I'm hoping is the root of her weight problem as she's otherwise clean, healthy and alert.

So far as I can tell, she's around 7 months of age. I weighed her last night at 48 paltry grams. the pet store has been getting her to sporadically eat f/t fuzzies and pinkies (mice). I plan on getting her switched over ASAP to rat pups (Tips on that appreciated).

I have her set up in a plastic shoebox with heat wire set to 90f. Still adjusting the tub for air flow and humidity stabilization, but the goal is 70%, we're almost there. I gave her a large crock for water and a simple box hide, paper towel substrate. I've since taped paper to three of the sides of the tub. She's within 4 feet of a window for photoperiod.

When should I try feeding her? What should I give, more fuzzy mice until she's regularly eating? Should I have her in a bigger tub? Is there anything I can do better? I want to give her the BEST possible chance of recovery.

Here is a small album of pictures I took last night.
