==Description== [[File:Bobbie 2010 2.jpg|thumb|The small tufts on a bobcat's ears are difficult to spot at even moderate distance]] The bobcat resembles other species of the midsize genus ''Lynx'', but is on average the smallest of the four. Its coat is variable, though generally tan to grayish-brown, with black streaks on the body and dark bars on the forelegs and tail. Its spotted patterning acts as camouflage. The ears are black-tipped and pointed, with short, black tufts. Generally, an off-white color is seen on the lips, chin, and underparts. Bobcats in the desert regions of the southwest have the lightest-colored coats, while those in the northern, forested regions are darkest. Kittens are born well-furred and already have their spots.<ref name=cah>{{cite book |author=Cahalane, V.
