Biting Clothing?

Whenever I wear a sweatshirt, Lola bites down on the material pretty hard and won't let go. Is this normal behavior? She hasn't bitten me, it just makes me a little worried because she hangs on for a long time and I'd hate to think how that would feel on my skin. I have seen hedgehogs do that with clothing. Most of the time it is because they are attracted to the smell of the detergent or some sort of perfume that is on your clothes. You could try switching to a detergent or fabric softener with less of a scent, or just continue using the same one and she should eventually recognize it and get bored of biting it.
