There are a lot of animals that are part of the cat family. Cougars and Pumas are just two of the creatures that you can find. Puma is considered to be the largest cat in the small cat category of this species. Take note that a lot of people consider cougars and pumas to be the same because they are mountain lions.
People may use these two terms interchangeably. One of the reasons why people call them differently depending on the location is due to that precisely. They can be found in various locations, so naturally, people had to come up with names to call this species. The word “cougar” seems to come from South America, while “puma” is the name that was used by the Incas.
