Oh my yes, both of my girls have very distinct meows...

Tabitha has a very deep and long mmmmmrrrrrrooooooowwwwwwww.... when she is about to give me a hairball! And when she is ready for me to come to bed, she walks to me and very quietly meows!

Sasha will meow quite loudly when she is looking for me, and then will meow again when she has found me!

Neither of them has a specific meow to tell me they are hungry, as they have trained me to feed them as soon as I walk in the front door from work!
