A months-old tiger cub is shown inside a veterinary clinic holding area recovering from dehydration Tuesday, May 1, 2018, at Gladys Porter Zoo in Brownsville, Texas. The cub was discovered by federal agents at the scene of a botched smuggling attempt along the U.S.-Mexico border. The alleged smugglers were able to evade apprehension after returning south across the Rio Grande River and the cub was taken to the zoo for medical care. (Jason Hoekema/The Brownsville Herald)
