FILE - In a Friday, Nov. 14, 2014 file photo, Elsa, a kitten, recovers at the Denver Dumb Friends League animal shelter, in Denver. A DNA study reached back thousands of years to track the spread domesticated cats through the ancient human world and found evidence of two major dispersals from the Middle East, in which people evidently took cats with them. Genetic signatures the felines had on those journeys are still seen in most modern-day breeds. (AP Photo/P. Solomon Banda)
