More people have eaten domestic animals than a burm ever would. I'd be more concerned about the foreigner down the street than a Burmese python in my backyard. Remember, they are vegatating ambush hunters, and they are mainly isolated in the wilderness. I must also mention that their numbers are much sparse- all this media about them is hysteria. In reality, you'll be worrying about American panthers or coyotes eating your cats or your dogs before a giant snake of any sort. (Unless your an idiot of a reptile keeper)
I think there are "bigger fish to fry" than the damn feral burns.
