Guest Cat (cat of our houseguest) really does have the "I'm dying" meow down. Unfortunately, he uses it to mean "I'm hungry," "I can't find you," "I don't want to be here," and "OH GOD THERE ARE OTHER CATS."

I have not heard this, but houseguest indicates that the cat can also, at will, do pitbull impressions. He is apparently a cat of great vocal talents.
