Some hedgies just don't like to be held or played with, as they like to do their own thing. My Penny is quite like that. I've had her for two years this summer, and she was from a rescue. She will hiss at me all day long if I try to interact with her, I just have to let her do her own thing. If I "ignore" her when she's out, she usually ends up coming to me, but it takes time. The shirt is a good idea, just make sure it smells like you (wear it to bed one night). Make sure its quiet and warm too when you take them out to make them as comfortable as possible. It is a patience game with these guys and it can get frustrating. Hopefully some more members will come along with more tips, I've just learned to accept my huffy ball of quills!
