My female normal is just under 11 weeks and the scale I ordered arrived today. She weighed in at 119g, which seems a little low compared to some of the other weights for comparable ages I've seen posted.
Her breeder recommended feeding her once weekly, and I've been giving her a F/T African Soft Fur every 7 days, plus an additional mouse after she shed and was acting all stalky. (Not sure how to describe it, but she was in the hunting pose she gets into under her branch when the mouse zombie starts to do a jig.) Out of curiosity, I weighed one of the mice, and it was 12g, almost exactly 10% of her body weight. We're planning to switch her to rat pups when we restock the freezer in a few weeks.
Oh, and she's just over 21". I've discovered the easiest way to check her length is to use my quilting mat, since it has a grid on it.
Is she too skinny? Should I switch to feeding every 5 days?
Thanks so much to everyone here. You have all been wonderfully helpful in raising our new baby!
