if her entire belly and undersides of legs and throat are white or off white, she could also be a fawn or fox (depending if its white or cream/off white) but I can't remember which is fawn and which is fox..though I think off white/ream is the fawn.

she's a pretty looking mouse. I used to breed them for fun and for food...when I had a townhouse and could keep them all in a separate room so the males didn't stink up the entire house. Now I have a one bedroom so don't breed mice at all anymore.
