One of my cats has a high voice and has learned to do perfect attention-seeking sad meows when she wants attention and is too lazy to find me, and sings a loud frantic song to motivate me as I prepare food.

The other one purrs with the depth and volume of a large diesel engine, but mostly only lets out her low raspy meow to complain, which could be anything from "open the window" to "why did you stop petting me for .5 seconds?"

If I were casting voices for them in some type of Homeward Bound-type movie, they'd be Mila Kunis and Jennifer Tilly respectively.
