Cats are evil!
"Cutaneous asthenia ("weak skin") is a skin deformity characterised by abnormal elasticity and stretching of the skin. Pendulous wing-like folds of skin form on the cat's back, shoulders and haunches. Even stroking the cat can causes the skin to stretch and tear. The flaps may include muscle fibers allowing some movement, but the cat cannot flap them in a bird-like manner though the wings may bounce up and down when the cat moves.
Cutaneous asthenia is caused by a collagen defect. Collagen is the protein that binds the cells of the dermis together. It is also called dermatoproxy and hereditary skin fragility or cutis elastica ("elastic skin") and is found in humans (Ehlers-Danlos Syndrome or EDS), dogs, mink, horses, cattle and sheep. In cattle and sheep it is called dermatosparaxis ("torn skin"). In horses a similar condition is called collagen dysplasia. The skin is also abnormally fragile. The skin flaps peel or slough off very easily, often without causing bleeding. This explains why cats with the condition suddenly "molt" their wings."
"One cat owner, known only as Feng, claims her cat's wings are a result of stress after he was 'harassed' by females looking to mate.
'At first, they were just two bumps, but they started to grow quickly, and after a month there were two wings,' she told Huashang News.
'Many female cats in heat came to harass him, and then the wings started to grow.'
And while she says her lovable Tom is no devil, his wings, which contain bones, make him look more like a 'cat angel'.
But genetic experts claim there is nothing angelic or magical about the condition, which doesn't hinder the cat's quality of life. They say the wings can form through poor grooming, a genetic defect or a hereditary skin condition."

One thing is for sure, whether these winged cats are demonic omens, the result of a skin condition or simply over stressed, it's a bad day for birds…
