I've had Draco for about 3-4 months, and he started to eat little pieces of my hair when he was about 1 month old. It's been a while since he's done this, but he started back up again. Is there a reason why he might be doing this? ( it's only when he's like sitting on my chest and see my hair and then he bites and starts eating it.) Is this ok for him to do? I eventually stop him but by then he's already got some eaten... worried....Help!
