My very timid kitty was acting ferociously and was making loud sounds as though he was ready to embark on a fight. When I looked around to see if which brother was posing a threat, I realized that neither of them were even in the room.
That is when I realized that he was playing with one of his favorite toys, a plastic bracelet (look closely). He got himself so excited that his fur was completely wild. I wish that I could have captured the photo a few seconds earlier so that you could see the full effect. I laughed so hard when I realized what the fury was all about!
