Haha, yes, I've been trying to describe that sound to my friends, and can't quite seem to work it out

. And they're not really that quiet, that was just a quiet moment, normally they're quite loud. Well, Piper is, anyway (hence the name). Every morning, at about 8:30, Mickey will suddenly go crazy, making this really high-pitched squeak, and trying to break out of the cage. I soon realised he does it because he wants to be taken outside! It's become a ritual, he squarks, I take them outside, they play and make noise, then he'll pipe up and make the same noise in the afternoon, letting me know to bring them back in.
