Moms are kind and gentle creatures, but don’t be fooled by their soft exterior. They turn into fierce fighters if they feel like their babies are threatened in any way, no matter how scary the opponent might be. The mama cat in the video below is the perfect example why you should never mess with someone’s kid. As soon as she sees a big dog close by and senses her kitten might be in dangerous, mama cat jumps into action. What follows much resembles a scene you would see in a movie about martial arts. Seriously, Jacky Chan has nothing on this cat.
