i fed my girl two small adult mice when they stopped leaving a lump in her. she was crusing around not even four hours ( HOURS ) later so i knew she was still hungry. i only did that for 2 feedings until i used all the small mice up and got the next size for her. she was feeding every 5-6 days, now im getting her on the 1x every 6/7 days thing because shes 9 months old and her prey are larger. she's happy though.
