she is not that big. she weighed about 500 grams when she arrived last weekend but my scale is not the most accurate. one mouse a week was definately not enough for this girl. She probably weighs more close to 570 grams in the pic because she has eatten 4 adult mice since 3/25. I hope to breed her next year. she is not that big huh? adam said he had some august hatchlings that were bigger
