I keep a laser pointer at my desk because my cat has figured out how to unplug my computer. Simply picking him up and moving him away from my desk doesn't stop him. Picking him up and tossing him halfway across the room doesn't stop him. Only the teasing of a little red dot can distract him long enough for me to get a few minutes of work done.
I live alone with my cat. Some people might think that would make me a crazy cat lady. But obviously those people have never met my cat.
My cat is a dick.
