When I first got my corn last summer, he was pretty good for handling. I could tell he wasn't thrilled about it but he got by. As the months have passed, he's gotten more and more shy about it. Now, he instantly wraps around my arm with his tail and gets real nervous whenever I take him out. I've read that corns tend to get better at handling as time goes on, so I'm wondering if I may have done something wrong or if there's anything I can do to make it better. I haven't dropped him or anything if that's a concern. Any suggestions?
