Hee! I clearly recall the very first time that Shansu the Balinese Kitty brought up a furball. She's normally a fairly quiet cat - she's very vocal, but she vocalises pretty quietly. This time, not so much. The first I knew that something was happening was this godawful YOWL OF TERROR from the hallway. It wasn't an "I don't feel so good" whine - it was more "ALIENS ARE BURSTING OUT FROM MY STOMACH! HELP ME! I THINK I'M DYING!" howl. A few moments later, aliensa furball did in fact erupt from her stomach. Whereupon she shook herself, gave herself a brief wash and wandered off to doze on my bed. Clearly scarred for life. :-)
