To be honest, I've never interacted with a dumerils that didn't seem to enjoy being handled. Every one I've been around (and I've known several - that's why I wanted one) has been quite content and happy to be handled and lounge on a lap or two. They aren't as active and maybe not quite as curious as red tails, but I never got the impression they didn't like handling. And they've all, including the males, been voracious eaters.

BUT, as I said, I don't own one myself. Maybe Paul from Moonlight will shed more light on this for us....
