I'm really glad you brought this up. I've always wondered about my 4 month olds appetite. I feed every 7 days but I give her 2 adult mice every feeding and she gobbles both of them in 10 min or less. And a few days later seems hungry again. She only comes out of hiding for food usualy and I alway wondered if I feed her too much but I figured she is just hungry and 1 mice obviously wasn't cutting it for her. In the last month she has gone from 169g to about 230. She eats in shed even and never misses a meal.
