how many mice to feed?

I finally got my 1 yr old BP (677 g) to eat again after a month off, but I went to F/T mice (arctic mice), even though I have a freezer full of sm rats ready to go. He's been eating 2 mice each feeding. I figure this is about the equivalent to a sm rat. But then I read that he should be eating 10-15% body weight, which means 70-100 g of mice. Thats a lot of mice! If he takes 2 mice, should i just try a third, fourth? I'm worried about regurg. Thanks for your help.

If you can get him to switch over to rats, give a 70g rat

I'd switch to rats if possible, too. However, if it's as much as he's supposed to be eating, I don't think you need to worry about regurge.
