The image was captured earlier this month by a camera set up in the Laguna Atascosa Wildlife Refuge on the Laguna Madre, about 20 miles east of Harlingen in Cameron County.
U.S. Fish and Wildlife Service wildlife biologist Hilary Swarts tells the San Antonio Express-News (http://bit.ly/1dnvtke) that she and colleagues "all jumped up and down and screamed" when they saw the photo.
Swarts says the kitten means the rare wildcat's population in the refuge grew from 11 to 12. She says it's believed the kitten is a female, adding to the breeding stock. There are fewer than 50 ocelots in the wild in the United States.
