Aw shucks, thanks.As far as longevity, I've had snakes live to mid-20's (25-26) years of age. But I don't know what typical longevity* is for longnose snakes, they're not commonly kept, partly because they're hard to feed. They mostly eat lizards or small snakes in the wild, but all things considered, it doesn't appear that mine has been harmed by a lifetime on mouse pinks & fuzzies instead. (*I'm guessing mine is pretty old at this point? Anyone else keeping them???)
