ConcinnusMan, I have a wandering that is about a year old and still tiny too! Ten inches to a foot is about right. No idea why this is, and he is super flinchy/skittish, and tries to launch out of your hand or musk you every time he's out. Is it possible that their poor temperaments are generated by their lack of size? Perhaps they are more insecure/fearful because they are still bite-sized?
