Just an opinion that i am suggesting.
I have owned many a Dumerils.
I am not saying that i am expert on them but i have noticed that alot of them that i observed did seem to be ambushers.
They like the thrill of the hunt ,more or less.
So what i started doing was feeding the animal in the cage making sure there is a hide box for the animal to hide in.
Then i would dangle the mouse in front of the hide where the animal is hiding by way of tongs of course.
It worked out that a good 80% of the time they would take the mouse with no problem.
Then when they really started to eat good,about four times of doing this in the cage i slowly started feeding them in a bin with a hide in it and started doing it this way.
And it ended up being about the same results.
This at least worked out for me and the animal i was working with.![]()
