Yes large mice, sorry still learning prey sizes! Haven't gotten a scale so not sure about weight she takes em w/no problem. If I had to guess a weight I would say 200-300g? no clue really she's about 3 months old though if you can imagine a snake that size/age range bigger than all the snakes her age though. Bought her from a colony of 300 that all hatched out within a few days of each other n everytime I go pick up food I peek in at the others who look like they've barely grown.
