No, that's not photoshop! "Winged cats" can be caused by a number of factors. THe most obvious is a bad case of matting. However, some cats have a genetic mutation where the scruff on their neck stretches out, but doesn't snap back. Instead, the skin stretches and becomes hard due to scar tissue. The wings even appear to flap as the animal runs. In superstitious areas, the cats are often killed, believed to be agents of the devil!
