Our male guinea pig will often stop in his tracks during his floor
time, exploring the house, and while keeping both front feet planted
firmly on the floor, he will rock his backside back and forth by
lifting one rear leg at a time, leg to leg, back and forth.
So what's this mean? Its very cute and definitely NOT popcorning. This
is a slow, very deliberate action.
My daughter says he's shaking his tail feather.
thanks
