Tigers, Panthera tigris, are the biggest cats of all, and they're the only large cats with stripes.
Most other members of the feline family are small, weighing 20 kg (44 lb) or less. Only lions and tigers reach weights of 225 kg (500 lb).
Once, eight subspecies of tigers roamed the forests of Asia. Now there are only five. Bali, Javan, and Caspian tigers were driven to extinction in just the past 50 years.
