That has to be the only downfall to breeding your own rats. I always had pet rats as a kid and it's easy for me to become attached to them. I bought her as a feeder but she was clearly pregnant so I kept her and she was such a good mom and super sweet so I just had to keep her. It was a win win anyway because my older breeder had a heat stroke and lost her eyesight so she is now retired (which is sad because she still tries to nurse the babies LOL).
And what is myco? I've heard of it before, just never looked into it. Maybe that's what happened with Little Momma... She suddenly lost a lot of weight and was sneezing a lot. She was covered in porphyrin.. It was pretty bad so I fed her off after a week of seeing no improvement.
