Since the glory days of the Indus Valley civilization, certain people have tried to teach their cats to talk. Perhaps this accounts for the collapse of the Indus Valley civilization. I mean, my cats can say “Meow” and that’s about it.
Anyway, here are a bunch of cats trying to say “Hello.” A few of them come fairly close to doing so. It is widely believed that Goethe had a cat that could say “Gesundheit,” but I’m afraid I cannot prove it.
