I'm not really sure what the gender is, but I'm pretty sure its a girl. Anyway, its 245 grams and I've been feeding it two 9-13 gram mice once a week. Its about a year and a half old. I've been following the Munson Feeding Plan but it stops at 170g+. How much should I be feeding it now? I order my mice from laynelabs.com. If someone could tell me what how big of mice I should get and how often to feed it that would be great.
