A pantera cat is not a specific type of cat. The term "pantera" is derived from the genus name Panthera, which includes big cats such as lions, tigers, leopards, and jaguars. In popular culture, the term "pantera" is sometimes used to refer to black panthers, which are not a separate species but rather a melanistic color variant of leopards, jaguars, and sometimes cougars. Therefore, "pantera cat" is not a distinct type of cat, but rather a term that can refer to various big cats or black panthers.
