Lucca is an indoor cat, but she's got plenty of wild instincts (Don't get me started!). A favorite pastime is what we call "watching kitty tv." She'll survey the birds at the feeder or the squirrels on the deck with riveted attention.
And she chirps! And squawks! I have never seen or heard a cat vocalize like this before--it is nothing like a meow or a hiss or a growl.
I've tried several times to record this crazy phenomenon. These little bits are the best so far. The first clip shows what Lucca is doing, while the second has more audio. Sorry for the poor quality; I'm no great technician . . .
