Not the growling noise. Ours does that when it's got the nose in the dish too quick and I take the bowl away to chop it up finer....she will growl. Especially if it's fresh meat or fish.
I mean the 'chattering' type noise that cats make when behind a window, watching the birds or hunting for flies. They sit bolt still, eyes fixed and just the jaw moves, making a 'clicking' sound.
Kinda like the subterranean killer in the Creep film
