You went to see the reason for these sounds, which led you to the highest floor. As soon as you entered the attic and opened the door, a whole pack of hungry cats rushed in your direction, which someone accidentally closed by their own imprudence. These unfortunate animals from Save The Cats ran forward not dismantling the road and fell down to the first floor. Immediately rescue the tail, otherwise they will all perish from fractures and injuries that are not compatible with life. Rather, substitute a hammock and catch all the animals that you only notice in flight.
