Nora is a loud mouth and anything that comes out of her mouth is full blast. lol Walter and Thomas on the other hand...they can both talk loud and normally (be here at meal time, HOLY MOLY!!), but sometimes, especially when they are on your lap or something (like just now I was loading the washing machine and Thomas was standing on it next to me), they open their mouths but nothing comes out. Not just once, either, they will keep doing it like they are having a conversation with you, but no sound ever comes out, just like a whisper noise. Kind of hard to describe. I've never come across or heard such a thing. It's weird, to be honest, but kind of cute. Do any of your cats do this??
