Chonker cat oddly enjoys standing on two legs

Says the parent of this cute chonker cat, "Riggs is 5 1/2 years old he's a domestic cat that we rescued when he was a baby. He's a very happy loving cat loves playing with his other cat friend and our two German Shepherds. He's been sitting up like that for as long as I can remember. And when his daddy comes to pet him he stands up."
