My female has taken only 2 small fish (haven't tried mice, the waste of food bothers me too) in the last 7 weeks (mated maybe 6 weeks ago), only worms will do. So that's what I've been giving her, with plenty of Nutrobal (vitamin+calcium supplement). She's been eating very well before, so I'm not worried (which is why I ask people if I should be), she's in good shape and hasn't lost any weight.
