My cat definitely has different sounds for different behaviors -- the most interesting one is when I leave the house and he didn't see me leave, I will get a notification from my nest cam that it thought it heard someone speaking, which will be my cat making a guttural sound that sounds eerily like "hello?" - he will sometimes do this if he can't find me in the house.

A second distinct meow he makes is when he is able to sneak past the baby gate to run down the stairs to the front door -- I call this his "see ya, sucker" meow.
