Just weighed the big girl tonight, shes up to 847g (not empty) from 830g a month ago, but still seems to be thin. She's more triangular that the ball. Anyway - I've been offering an adult mouse (ranging from 18-25g) every 5 days. These don't make a noticeable lump at all. I'm just wondering if this prey size is too small? She is always ravenous, strikes immediately and looks for more, but I don't know if this is just a corn thing or if I need to order jumbo mice instead. I don't want her to go to her forever home until I have her feeding worked out - so any advice in appreciated
