Colossal Kitties. Tigers are the biggest cats in the world, and Amur tigers are the biggest subspecies (type) of tigers. They stand about three feet tall at the shoulder. This isn't quite as tall as a lion, but Amur tigers are longer and usually weigh more. Adult males can grow up to 11 feet long and weigh over 600 pounds; females are smaller -- up to nine feet long and about 370 pounds. Now those are some big kitties!
