Having been with an engineer and a cat for about 14 years (the engineer just a bit longer than the cat) I can say that was one of the funniest things I've seen in a while. The cat yodeling especially. That was a practiced art of discipline with my engineer (it got really bad when he started trying it with me!) Maybe now that he is gone, I should pick it up with the cat again. Perhaps, that's why she misbehaves so much now? She misses it?
