Things there should be words for, but there aren't.

The noise that cats make when they stand up and sort of shake their head, or shake themselves off, after they've been sleeping or lying down for a while, or if they've gotten wet, or something got in their ear. It's harder to hear if the cat has bells or metal tags on their collar, but there's definitely a distinct noise they make-- some of it is their ears flapping, I think, but I'm not sure what the rest of it is from.

Anyone else know what we're talking about here? Can you think of a good way to transcribe the sound?
