Dumeril's are hardly an expert level snake but they have some quirks.
For one, they like it pretty hot but you can't bake 'em or they will have shedding problems.
Mine is very gentle once outside her tub.
You cannot go in an grab a Dumeril's like a RTB or BP. You will get nailed sooner or later. I think we all agree some snakes are rather gentle biters while others are mean, hard mofo's.

I would not want to get tagged by my Dumerils.

She bites hard and she's the fastest striking snake i've ever seen personally. From a dead stop with
pine shavings on her head she will hit a rat so fast you can't believe it.
But when you take her out there's no problem.
She will not eat when shedding.
She has gone off food in the winter which is frustrating.
She is a very strong snake. IMO, she is stronger than any other Boas and even Retic's and Burms the same size. You can feel it.
So are Dumeril's "Beginner" snakes? Beats me. *shrug*
I'm sort of guilty of what A.gigas describes, though i'm 42 as of yesterday and have been keeping reptiles for years. My position changed a bit and I underestimated my availability to this snake. With two little kids, cats and two dogs I can't handle her enough and frankly don't need a 6-7 ft snake that isn't handled enough. This is a tough decision for me as I intend to keep stuff forever when it comes to animals (My BP is now 14 yrs old or something like that) but I have to fess up to the fact that she was the wrong pet to get; I made a bad decision.
