Most people like autumn because of the change in color of the foliage. Personally it is the dramatic lighting changes that excite me but cats also love autumn. They just can’t help it. Cats are wired to react to small moving objects as a predatory instinct. When autumn comes around, my cats become hyperactive, batting with their paws as if they are going to catch the falling leaves through the window glass. When I do take them outside it is sensory overload for them. There are just too many falling leaves to keep track of. They chase the leaves and leap into the air tying to catch them before they hit the ground.
