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.
And all cats utilize their sensitive whiskers to act as a radar detector to help locate prey. Cats are mostly solitary. However, tigers will congregate in groups when prey is plentiful, as will domestic cats who live outdoors. No feline but the lion hunts as a team, as canines do. Markings on wild cats vary greatly, as determined by their habitat.
