Actually Kai, that's just a stereotype. I myself have had several cats that did actualy quite enjoy water. My current (now older cat) loves to get baths, she loves to sleep in sinks with the water tap running, and she'll go swimming in a tub of water. It really depends on the individual cat.
My little Kimahri (Named after Kimahri from Final Fantasy X) hated water. She HATED it. She hated everything, though.
Then again, my little rat Yuna (Named after Yuna from Final Fantasy X) loved taking baths. She was mostly white, with a few tan patches, and dark red eyes. She died at three years old, and is buried in my grandparents' yard.
