Chuy knows which side his bread is buttered on, loves his comfort, and likes his prey not to know he is on to them. Praline and Mochi don't care who knows, and they swagger around, lobbing Haka like some other dogs chase bubbles.
Shortly after this photo was taken, Praline managed to squeeze through the square hole. Meh. She emerged with blood on her face that apparently didn't come from her. Since she was not carrying a carcass, I assume the little blighter got away. Better not come back.
