From Defenders of Wildlife:
The most common wildcat in North America, the bobcat is named for its short, bobbed tail. They are medium-sized cats and are slightly smaller but similar in appearance to their cousin, the lynx. Their coats vary in color from shades of beige to brown fur with spotted or lined markings in dark brown or black.
Though bobcats are only about twice the size of a full grown domestic housecat, they can bring down prey as large as an adult deer nearly ten times its own weight!
