well when i got her the mouse they fed her was about 3 times the size of a hopper and they fed every 10 days she is about 5 months old and i started giving her 2 hoppers every 5 days. Well today i bout 2 weined mice is that the reason the size didn't look like it was that different. i have kept the mouse and i was wondering when do i try again or do i not and should i just go up one size and get one or stay with what i did today or go back to the 2 hoppers
