For more than a decade, the magicians ran a stage show at the Mirage famously featuring a variety of big cats. Their regular run came to an abrupt end in 2003, however, after Roy was reportedly bitten in the neck and seriously injured by a male white tiger they'd forced to perform.
Since then, the pair continue to be a presence at the Mirage, lending their name to an exotic animal attraction, Siegfried & Roy's Secret Garden and Dolphin Habitat - home to numerous big cats, as well as a miserable pool that has claimed the lives of 22 marine mammals.
That said, despite the wholly unnatural existence that awaits these four tiger cubs, set alongside the gaudy spectacles of the Las Vegas strip, it's all for a good cause, supposedly.
"Our newest 'Ambassadors of Conservation' play an important role in our never-ending quest to protect these animals," Roy said, according to a press release. "It is imperative to continue our conservation efforts to save these magnificent tigers for future generations to enjoy and cherish."
"It is always exciting to welcome new members to our family at The Mirage," added Siegfried.
