Bobcat (Lynx rufus)                                Bobcats, also known as wildcats, are much smaller than mountain lions and have shorter tails.  These cats do well around park borders of urban Tucson where food like rabbits and quail are abundant.  Despite their relatively small size, reports have cited bobcats preying on animals as large as adult deer!  Their usual diet consists of small mammals, birds, and carrion.  They are about 2 -4 feet long and weigh from 15 to 29 pounds.
