After cat-sitting for a friend for the past three nights, I am rethinking my desire of getting another cat, as for the past three nights kitty has awakened me in the middle of the night with his constant yowling, just for the sake of hearing his own voice. I can hear him through ear plugs, a closed bedroom door, and a fan in the window on medium speed. Sorry kitty, tonight you will be banished two floors down to the basement.
