Rat wont pee on beding

Question
Hi, my rats name is Sophie. ever since I got her she has been using her carefresh bedding. even at the pet store I got her from they used carefresh. About two weeks ago Sophie started to pee on one of her three levels. Then a few days later she started pooping. I tried washing it with vinegar and water but that didn't work. What do I do?

Answer
You might want to try getting her a litter box with a little bit of bedding in it and put it up there on the shelf, and see if you can potty train her. It would be much easier than cleaning the whole cage every week, and most people try for ages to successfully potty train their rats -- but she's already hitting a step in the right direction!
