I don't know how much she weighs, I've been leaving her alone for the most part because of the move, shed, and feeding. Her previous owner said she was 6ft, 30lbs, but she doesn't feel even half as heavy as my son and he's 32lbs. I agree 3 Rats was probably too much in retrospect, even if they were on the small side. Her previous owner said she was fed a jumbo rat every 2 weeks or a large every week. This seems fair to me, but I'm new and that's why I'm asking the question here. No I didn't see any bubbles.
She is kept in a 4'×18"×12" plastic tub with a two large heating pads side by side under it to give her about a square foot of heated space and 3ft to get away from it if needed. The tub came with her and I supplied the heating pads and put newspaper bedding down. I don't have heat or humidity readers yet. Please don't rip me one for that, I know they're needed and I intend on getting them soon. A coworker gave her to me because she couldn't take care of her anymore.
