How old is she? My guy is about 6-7 mos right now and 270g I had him on fuzzy's when I first got him then moved him up to a fuzzy and an adult mouse for a few weeks now he's on 2 adult mice a week and I'll be moving him up to 3 adult mice next week. He had no problem switching to the adult mice however I feed him what he was already eating then offered the adult mouse second and he had no issues taking it down. Hope this helps![]()
