While they have a reputation for being nippy and feisty, it's really not much more than your "average" baby ratsnake. My friend who breeds them seems to have mostly calm ones. Mine would bite me when I first picked him up then settle down right away. It took a few months of handling 3 or 4 times a week. And when I really stop and think about it...he only drew blood a couple of times. I just handled him this morning, and he is great. Maybe a little more "active" but not mean at all.
I think I appreciated him more since I had to work with him a little. When he was small, I was determined to "tame" him and even used latex gloves for a short period since I had heard that they dislike the taste. Most likely the biggest advantage of the gloves was that it made it so that I did not hesitate to pick him up.
Bottom line: If you want a leucistic snake, get a texas rat. If you have the chance to go to a show where you can compare prices, "attitudes" and even bug-eyes...by all means go. When the leucistic texas rat starts to get bigger it is a very impressive animal. As long as you tame them when they are little(and it is usually NOT a problem) they are awesome. Duffy
