So I went to that place. Unfortunately they do carry rats, but the ones they were selling were still too large. but I did get a great deal on some mice larger than the ones she's been eating which should do her nicely until she's ready for rats.
On another note, I still haven't gotten any poop from her, but I weighed her this afternoon and she went from 173 Grams on Friday before her feeding to 195 Grams this afternoon! She's still not where she's supposed to be, but she's well on her way considering october 1st she was only 151. Thanks to you guys and your helpful advice she's gained quite a bit very quickly.
