Yes, I exchange greetings with animals.
Cows - "Moo"
Goats & sheep - "Baa"
Cats - "Hey kitty"
Dogs - "Hey pup"
Barking dogs - "RRRRoof! Good dog."
This reminds me of a comedian I saw, back in the early '80s. I think it went something like this:
Why do we moo at cows, when we drive by?
Are we trying to fool them?
Are they supposed to think, "Hey! Is a cow driving that car? How did she afford that?"
