OMG, we go through this every.single.day. She loves pulling the cat's and dog's hair, I have no idea why! And because we have kept her and the cat separated as much as possible since she was a newborn (cat still has its claws), she just wants to get at him that much more! And, like you said, she just LAUGHS in my face when I try to tell her no. LOL.
