Cats in the United States
Many different species of mammal can be classified as cats (felids) in the United States. These include domestic cat (both house cats and feral), of the species Felis catus; medium-sized wild cats from the genus Lynx; and big cats from the genera Puma and Panthera. Domestic cats vastly outnumber wild cats in the United States. Prehistoric cats At least 67 species of sabertoothed cats existed in North America between 42 million and 11 thousand years ago before going extinct. Their disappearance can be attributed to both the changing climate at the end of the Ice Age and the appearance of humans in the Americas. Some prehistoric animals referred to as "saber-toothed cats" were in fact marsupials and not cats at all, but called such because of their resemblance to true felines with large canine teeth. Big cats Two main species of big cat once inhabited the United States. One is the jaguar (Panthera onca), which is related to many species of big cat found on other continents. Though there are single jaguars now living within Arizona, the species has largely been extirpated from the United States (in the states of Texas, Colorado, New Mexico, and Louisiana) since the early 20th
