Thought it was time for you to hear Mr Darcy and Sookie for a change. They do like to chat! This is their "I'm hungry gimme food" voice.
They have several other quite distinct noises too, I think I've become quite a good Cat Whisperer. There is the "teehee I'm about to be naughty" chirrup, usually performed whilst running or jumping onto/off of something, the "I'm at the other side of the house and no-one is playing with me" meow, the "get off me Mr Darcy I don't like my ears being bitten" squeal and the "ha! Tricked you, now I shall pounce and bite YOUR ears!!" trill. And there are many others too... do your cats talk to you?? =^..^=
