I didn't live with a feline myself until I moved into a group house at the University of Maryland, and my first roommate there had a cat, Yay Yo. Yes, that was really his name. Yay Yo was an outdoor cat, and he would be gone for long stretches of time doing God knows what. Basically, he did whatever the hell he wanted for the most part, and that included when he was in our cramped little room. One day after class, when I was lying down for a bit, Yay Yo helped welcome me by jumping from my roommate's lofted bed to mine, landing directly in a, um, delicate place.
