Animal advocates have been trying to stop organizations and businesses that profit from photo ops with tigers, like Tiger Temple Thailand, for a long time. Places like these often take baby tigers away from their mothers at an early age, sometimes removing their claws and making other cruel alterations to the cubs in order to allow humans to hold them.

UPDATE: While some commenters have pointed out that the latest photo was taken at the Black Jaguar White Tiger Foundation, a Mexican sanctuary that rescues big cats, so-called "tiger selfies" are still a bad idea. Not only do they cause stress to the animals, but Susan Bass, PR director for the Florida-based sanctuary and advocacy group Big Cat Rescue, pointed out that they promote false perceptions of big cats. "[They've] had a lot of celebrities visit and pose with the cubs which we're very much against, because it says that they're good pets," she told The Dodo. "To touch them, we don't agree with."
