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!
Red squirrels might be a little bit bigger or smaller in some place, but they weigh 200 to 250 g on average. They are 270 to 385 mm long. This includes their tail, which is 92 to 158 mm long by itself. Their back feet are 35 to 57 mm long and their ears are 19 to 31 mm long. (Hall, 1981; Kramm, et al., 1975; Lindsay, 1982)
