Characteristics A ll cats, from the largest tiger to the fluffiest Persian, share a surprising number of similarities.
Felids have large eyes with binocular color vision.
In daylight, they see about as well as we do. However, under poor illumination their sight is up six times as acute as ours. Their eyes adjust immediately to sudden darkness. When it is so dark that even their keen eyesight fails, cats use their excellent hearing. Small cats are particularly adept at picking up the kinds of high-frequency sounds made by rodents.
