Please take her from them. They don't care about her. Initial set up: 41qt sterilite 9 dollars, aspen bedding 10 dollars, 3 pack of FT small rats 6 dollars, UTH 20 dollars. Then post back on here. You'll need to monitor humidity and temperature, going the cheap route which is fine for now is 11 bucks at petco. Get a membership and start saving lol I spent 20 free dollars today from mine. She needs a clean water bowl without shedding in it. She needs 2 hides which you can make, you can even use a walmart paper bag or now. There have been worse that I've seen on here but still I would take her in a heart beat. What size tank did you buy? The 41qt is cheap so buy one of those and take the tank back. Take the hide back too. The sterilite is recommended over a tank in part because it will hold humidity better. Having said that you will need to poke holes in it to make sure it does have airflow. Now I'm going to be worried lol
