When we got her, the expo we got her at was all sold out of F/T rats so we had to get the largest mice they had. But she'll only eat one; I've tried offering more but she has no interest after the first one.
We're just waiting for her to poop so we can take that in to the vet with us for a fecal test. She went in about a month and a half ago and was diagnosed with a mild RI, but we got the oral Baytril instead of the shots. Looking back I kinda wish I had gotten the shots, I heard that the oral meds are pretty much useless.
She's not losing weight, she's just gaining weight VERY VERY slowly, if at all.
