Yes, as well as "cat-talking" to all my cats, I also talk back to them in their own language. Big's meow is more like a squeak, and I have a fairly deep voice for a woman, so I usually can't copy him. But Cookie and I often "woo" to each other, and Peaches and I always "mow" to each other (she leaves the "e" out of "meow"), and Pepper seems to think my name is "Brent" because that's what it sounds like she is saying to me.
