A man who suffered "significant" arm injuries after allegedly sneaking into the tiger enclosure of the Calgary Zoo appears to be the latest case of misadventure involving a big cat at a metropolitan zoo. As Monday's incident is not the first time that a member of the public -- or a zookeeper -- has been seriously injured, or killed, after getting too close to a big cat being held in captivity.

Last year, a Scottish teenager was bitten by a white lion at the Zion Wildlife Park in New Zealand after she put her hands through a hole in the fence. And in the first half of this year, two zookeepers were mauled -- one fatally -- in separate incidents by the same white tiger at the same zoo.

Last summer, a Japanese zookeeper was mauled to death while cleaning out the cage of a 150-kilogram male tiger. Police believed the zookeeper had failed to lock the door to the cage, which allowed the tiger to get inside the enclosure at the same time.

Nearly two years ago, a teenager died at the San Francisco Zoo after he and his friends allegedly began taunting a Siberian tiger, while standing on the railing of its enclosure on Christmas Day in 2007. The tiger escaped her enclosure and mauled the teen the death, and injured two other people. The tiger, named Tatiana, was shot to death by police.

The zoo has since upgraded its enclosures, but it hasn't stopped members of the public from trying to gain access to its larger animals. Only last week, the San Francisco Chronicle reported that a man sneaked into the grizzly bear exhibit, but escaped injuries after zookeepers quickly saw what was happening and quickly took him into custody.

And in May 2007, a 32-year-old woman died after being clawed by a tiger at a private zoo in British Columbia.

Three months before, in February 2007, a six-year-old girl died at a zoo in China's Yunnan province after being bitten to death by a tiger. She was standing behind the tiger, posing for a picture, when the attack occurred.
