The mortal has a gun that will shoot me if I do it. Now stop posting and do your homework or whatever your busy at.
I wish to be a cat so I can sit around in the sun all day and go nuts over the other cat that keeps coming to my home asking for food. It's my home. My food. Get away before I break through this glass sliding door and scratch you to oblivion. But seriously. I'm upstairs and I can hear my cats flipping out on the door whenever the cat comes by. And all she does is ignore my cats, just asking for food.
