Wingcats

Fan art for Clare Bell of three characters appearing in her online novelette "Ratha's Island". Google for it if you'd like to read it.
These aren't simply cats with wings stuck to them. They have a highly developed language that involves ultrasound, they have special muscles to help them fly, hollow bones and even a little tail-fan that I didn't draw that helps them stabilize in flight.
