A 'late' friend of mine used to keep them, they were his favorite snakes. He enjoyed their attitudes, & one of his would actually stop just short of sinking it's teeth into his hand- he got quite a kick out of that. Of course, there's no telling if the snake suddenly realized this was his buddy, or if he just didn't taste all that good, lol, but my friend took it to be a indication of acceptance. I hope you can find some captive-bred ones, as otherwise they're going to be heavily-parasitized & difficult to manage (health-wise), & they enjoy large arboreal type enclosures.

If you can't find these, you might also enjoy Taiwan beauty rat snakes (they get bigger but captive-bred are readily available- I used to keep these) or "Blue beauty" Vietnamese rat snakes. Both of these have similar care needs & personalities, more like a racer when you handle them- & don't expect them to sit still.
