Just off hand I know Valory has a loud purr and an "ick, ick" noise she makes when she wants attention. Lil Guy has a mmmrrrrrrr or mmmmeeeerrrrrrrr noise. Kismet doesn't "talk" often, and I'm ashamed
to say I don't know what she sounds like. Something sort of soft and short. (I swear she's not neglected. But with three other cats in the house, she rarely has to tell me anything, because they take care of it for her.) Baby Girl says a demanding "Me-oow!" and runs to the kitchen so I know her food dish is running low. That's about the only time she talks either, but I definitely know what she sounds like.
