Actually, my boyfriend and I have thought about this as well. We know of a theft here in town with a local breeder losing all of his morphs. While microchipping cannot be used to locate them, you can register with any of the companies to prove ownership.

Here is another scenerio for you, what if there is a natural disaster and your snakes are able to escape. Having your snakes microchipped will help you to be able to identify them. Plus, here in FL, they are trying to get that microchipping is mandatory for all ROC reptiles (ok, so Balls are not on that list, but still, you get the point).

Even the SPCA are now microchipping all animals that are adopted out regardless of what they are.

Bottom line, if its something that you want to do for your own peace of mind, then do it. They are your snakes and your opinion is the only one that matters in that regard.
