On the subject of vocalizations, both my cats Xander and Miuccia purr, but neither cats make the traditional "meow" noise.

Xander makes a lot of different "yeows", including one that sounds a lot like hello ("yaaaallwooooo") when he greets me in the morning, and certain types of yeows when he is hungry. What is more unusual is that in the morning, Xander barks like a little dog ("roawp, roawp, roawp") in order to make sure everyone wakes up.

Miuccia usually doesn't say anything at all, but when she does, it is a hoarse sounding "aaarh!".
