Here's a diagram from the National Park's Santa Monica Mountains site showing the relative size and color differences of a mountain lion, bobcat and house cat:

Bobcats are found through out the continental US, most of Mexico and some of southern Canada. The average bobcat tips the scales at about 18 pounds. They are primarily nocturnal and the best times to see them are early morning or dusk. Bobcats are solitary and territorial with males marking a territory of about 3 square miles and females with territories of 1.5 square miles that overlap with males' territories. For reference, a square mile is 640 acres, so these cats cover a lot of ground. Bobcats are adaptable and can live on the urban edge, provided they find food.
