This because last month Corbin had vice grip jaws on a mouse I tried to take away from him. The more I tried to pry his jaw open the harder he clamped down on poor mouse. When mouse eyes glazed over, he gave it up. In awe of power of house cat. No less than pit bull in strength. My badass cat, I love him. PS: mouse went to outdoor magpie bowl, where the carrion birds found and took him away, thankful for the free meal.
