Lord yes. Both of mine chirp, although one does more than the other. Wobbles doesn't talk much, but when she does, its usually a little chirp. Minette talks CONSTANTLY, sometimes a full-throated meow, but usually the little "murr" sound that sounds so much like a bird.

On the same line...does anyone else's cats try to imitate birds? I've had two kitties that do this. Minette sits in the window, stares at the birds, and, well, makes noises just like them! Her big brother Ozzie (who's currently living with my mother) used to do the same thing.
