Arnold has a habit of "getting into trouble" to get my attention. He is so comical that I mostly allow it. He has taken to getting behind the PC monitor. At times he claws at papers which, thanks to my "housekeeping" skills, are plentiful.
I take Arnold outside on a leash but let him go free and watch him constantly so he stays in the yard. Being a very smart cat, he sort of knows the limits. He loves to go out and just lay in wait for a chipmunk to come along.
