CRAZY CAT ATTACKS MAN

My neighbor wanted me to feed his cat while he was away for 2 weeks. Each time I went up the cat acted more hostile than the time before, but I had to go up. He needed to eat, and he needed fresh water. This particular time he was so aggressive that I decided to film it. I did nothing to provoke the attack, he just didn't want me in his crib I suppose. I blame it on him being territorial, and his owner being gone for about 2 weeks at this point.
