Tomorrow I am going to pick up a Dumeril boa. From my understanding the young boy can not get it to feed on a regular basis. I always do research on any reptile before I buy it. After listening to how it was kept in its cage and substrate I think I have found out what the snake needs before it will feed properly. His mom said she might also have all the vet records to see that it has a clean bill of health.

These snakes are ambush hunters. They like to burrow then explode on there prey. (From what I have read)
After reading everything I could find on these snakes I am wondering if the substrate should be aspen or coco fiber. Which one would be easier for the snake to burrow in. Which is going to be more natural for it.

Any other tips or tricks for getting a Dumeril to feed would be appreciated.

I honestly think the snake is not eating because it needs a little better care.
