Nobody's exactly sure where the winged cats residing at Salem came from. They are rumoured to originally be a failed Transfiguration homework that fled from its creator and multiplied. At first the staff tried to get rid of the cats, setting up traps and trying to lure them into closed rooms, but after a while both they and the students grew too fond of them and decided to let them be. Nowadays they can be seen lazily soaking up the sun on the rooftops or gliding through the corridors, chasing mice. Some alumni has adopted specimen of the felines to keep them as pets after graduation, but other than that the winged cats can’t be found anywhere else than at the Institute.
