The majority of my snakes get 1 or 2 appropriately sized prey item(s) every 2 weeks.
Duncan - Colombian redtail boa (26 years old) = 1 xl rat
Eli - Normal BP (28 years old) = 1 med rat
Hudson - Colombian rainbow boa (30 years old) = 1 med rat
Merlin - Solomon Island ground boa (18 years old) = 1 adult mouse
Yin & Yang - Corn snake pair (16 years old) = 2 adult mice each
Buttercup - Albino BP (3 years old) = 2-3 adult mice because he refuses rats
Artemis - Dragonfly BP (3 years old, new addition 9/2/18) = offered 1 sm rat (has not fed for me yet)
These 3 are this year’s hatchlings and are offered prey weekly.
Piper - Pied BP (7/2018 hatchling) = 1-2 f/t hoppers
Belle - Lemonblast BP (7/2018 hatchling) = 1-2 live fuzzies
Button - BEL BP (May/June 2018 hatchling) = 1 f/t adult mouse
Almost everyone has good body mass, not skinny by any means, but not particularly chunky either. The only exception is Belle, who is trimmer than I’d like because she’s a picky eater and refused food for the first month I had her. She’s finally eating weekly, though not the size prey item I’d prefer. Once she eats a few more times, I’m going to try rat pinks. They are a large jump in size from the fuzzies she is accepting, but they are the next size live prey my shop carries. Occasionally somebody will get an extra refused rodent from one of the other snakes, but not often. I have a few snakes that would easily eat enough to get significantly overweight. If I notice them getting a little too thick, I bump the feedings back by 1 week.
