Catwalk has now been taken to a wild new level with a Japanese zoo using its fierce inhabitants to rip up jeans for a fashionable look.
The facility northeast of Tokyo has unveiled "Zoo Jeans", styled by the fangs and claws of lions, tigers and bears.
Zoo officials said the material held up well, all things considered.
"We wrapped several pieces of denim around tyres and other toys. Once they were thrown into the enclosures, the animals jumped on them," said zoo director Nobutaka Namae, adding that the pieces were later patched together to create the finished product.
"The denim was actually much tougher than we had thought, and it turned out nicely destroyed."
The idea came from a Tokyo advertising executive who wanted to give something back to the zoo where he spent time as a child, Namae added.
Two pairs of jeans ripped by lions and a tiger-destroyed version are being auctioned on the Internet with proceeds to be donated to the zoo and the conservation group WWF.
As of Monday, bidding on the tiger-torn denim had soared to 121,000 yen ($1,200).
They will be on exhibit at the Kamine Zoo -- along with a bear-savaged version -- until next week.
