Which is the most powerful predator on both land and trees?

The Puma is a large Cat   found in the mountains from Southern Canada to the tip of South America also commonly known as  the Mountain Lion. The Puma has no markings on its fur leading to its scientific name Felis concolor which means 'cat of one color'. They have pointed ears and their acute hearing allows them to detect prey even when it is too dark for them to see. Puma can easily adapt to their natural habitat, they can hunt both on land and on trees comfortably.  This big cat unlike other member of their family is not able to roar.  Puma cubs are born blind and are completely helpless for their first two weeks of life until their blue eyes fully open. The Puma is a large and powerful carnivore, hunting and eating only other animals in order to survive. The Puma is one of the most dominant predators throughout much of their natural environment and are therefore rarely preyed upon by other species.   The biggest threat to the Puma however is people who have hunted this large Cat. In some areas they are also hunted by ranch owners who blame Pumas for their loss of  livestock.
