Thanks for your informative input. although I think there's a certain point you didn't get it right. Maybe that's because I didn't make it clear.Sorry for that.
"Feeding 30% of their body weight, which is what your doing by feeding two prey items a week is excessive. " as you put it. That's not the case. When she was 374g I feed her 2 mice weights 60g in total every 5 days . 60/374=16%, and now it's still 2 mice when she reaches 500g,that's 60/500=12%. It's nowhere near 30%, so I suppose it's on a healthy diet. Other than that, I totally agree with you ! As for appropriate-sized rat, that's what I've been having trouble getting my hands on, it's just kind of hard to come by in my city. But I'll keep an eye on it. Thanks for sharing.
