I wonder what a cat with wings would be like? Would they flap like a magpie or a bat? Would they chase birds in the sky, like Sparrowhawks? I can imagine them flying up to the tree tops. Nesting in the very top branches, feathering their nests? I’d be worried for the health of small mammals too, the bat cat would dive from great heights instead of simply pouncing from a short distance away. Beware genetic manipulation!
