The Bobcat has powerful jaws and long, pointed canine teeth. It has sharp, retractable claws, big short ears, and a spotted coat. Many bobcats have long tufts of hair at the tip of the ears that improve the cat's hearing. The brown eyes have round pupils. These graceful cats are from 24 to 40 inches (60–100 cm) long (including the tail). The stubby tail is only 4 to 7 inches (10–18 cm) long, and looks as though it was cut off (or bobbed). This is what this cat is named for. They are nocturnal (active at night) and elusive so they are rarely seen by humans.
