Heidi does the general cat things such as bringing in dead and half dead birds, knocking things over, but she's also developed this strange and slightly alarming habit of chewing on thumb tacs. For whatever reason (probably cause she never swallows them) these never seem to damage her health. I also have some amusing pictures of her.
