I have a 3 year old cat (Kitty) which does a little something "different" when she's being petted on his back. About 2 inches from her tail, if it's even touched, she will start to chew on anything near her mouth, usually her paws. If there's any toys or strings near her, she will definately get to that first and chew away. It's not a behavior that seems dangerous to her, she seems to love it, I'm just not sure why she does this. As soon as I stop touching her back, she stops chewing, but the second I pet her, she's right back at it. Any ideas or thoughts would ease my curiousity. Thanks. Gina
