My wife used to chide our brother and sister cats, Buster and Missy, for indulging in “punchy hands and frowny faces.” They never did it while we were there. But if we went out to the store or something, we’d come home to find the living room littered with tuffets of white fur and two cats pretending nothing had happened. Our rats used to do that, too–as soon as we turned out the lights for bed.
But don’t fret. None of the animals in this video is at all serious about hurting anyone. They’re just scrapping.
