Conceived and designed by the Japanese animal advocacy group the Mineko Club, each pair of Zoo Jeans promises to be "The only jeans with the design in the world."
"The wild rips and tears in Zoo Jeans have been created with pure animal instinct," according the Zoo Jeans official website.
"Zoo Jeans are the only jeans on earth designed by dangerous animals. We first take their favorite playthings -- old tires and giant rubber balls -- and wrap them in sheet of denim. Then we return them to the animals and let nature take its course."
The fabric is then removed from the toys, and the most fashionable remnants are cut and sewed into a pair of jeans.
Two pairs mauled by lions and one mauled by tigers sold at a Japanese auction house for $3,500, with one pair of the lion-distressed jeans selling for $1,500. The Mineko Club kept the pair mauled by bears.
A large portion of the money was donated to the World Wildlife Fund Japan, whose director of communications, Akiko Ishihara, told CNN Money that although the group accepted the donation, they are less-than-thrilled about how the money was acquired.
"In principle, we don't raise money by using animals in this way."
