I think most only feed once a week. This gives their digestive tract time to rest in between feedings. Some wait to see poo before feeding again. Just make sure you give enough at the one meal. I feed mine two prey items that are appropriately sized, then wait until a day or two after the poo to feed again.
:Ok, i should be getting my new baby BCI girl in 2 days. I was talking to the breeder, and he said that he's been feeding her two pinkies a week, but that she really only needs to be feed once a week. I was wondering should i just feed her once a week?
