I have four dums, an adult male and 1.2 yearlings. The yearlings are fed every 10 days and will be pushed out to every 14 days at the end of this year. They get feeder rats that are just slightly smaller than they are at their widest point and leave a minimal lump.

The adult male is fed every 14 days but he gets a one-pound rabbit that is about 3/4 of his thickness.

Dums run cooler than BCI's or BP's, 75-85*F, so they need more time to digest their meals. Feeding every 10-14 days should be fine.

Dums are ground boas and ambush predators - in the wild they burrow underground with just their nose poking out waiting for prey to wander by. I like to see hunting behavior for 3-4 days prior to feeding day.
