Tigers and lions are among nature's grandest predators. A grizzly bear may be larger than a Siberian tiger, but the tiger is much quicker. A wolf may have a better sense of smell than a jaguar, but a jaguar can handle large prey alone while wolves hunt in packs. Cats have excellent night vision, sharp hearing and enormous physical strength. They sneak up on their prey; the camouflage patterns in their fur and their graceful, quiet movements make the cats difficult to notice.
