Callie is the only real talkative one...(she's part siamese) but she only meows when she wants water from the tap, or her toy got stuck under the couch, etc. It's not a persistent non-stop meow..thank goodness!!
Whisper learned from Callie to get my attention from meowing..that's pretty rare, however, and he only does it when he wants lovies...
Shadow hardly ever meows...she really only meows to me if she knows I am talking directly to her...and lucky for me, they are very good about letting us sleep in!
