The bobcat (Lynx rufus) is equipped with razor-sharp claws, needle-like teeth, and the strength to make good use of these weapons. About the size of a medium-sized dog, male bobcats average 39 inches in length and weigh about 24 pounds, while females are closer to 36 inches in length and 15 pounds in weight. The bobcat is so named because of it's 'bobbed' tails, which are usually 5-6 inches, although tails as long as eighteen inches have been recorded!
Male bobcats are slightly larger and heavier than females. Most adult males weigh 20 to 22 pounds, while females average 18 to 19 pounds. Individuals may be much larger at times, especially in the northern states where many mature males may weigh 30 pounds. The heaviest recorded bobcat was taken in Maine and weighed 76 pounds. Bobcats have short tails of 5 to 6 inches in length. The underside of the tail is whitish, and there is a black spot near the end of the tail. Lynx can be confused with bobcats in northern areas, but the lynx tail is totally black, top and bottom, over the entire end of the tail.
