Kanye West has undoubtedly enjoyed a lot of success with his various fashion lines and Air Yeezys and the like, but one thing that he hasn't won plaudits for is his use of fur in his creations.

That hasn't gone unnoticed by Sia, who took to Twitter to implore the rapper to think twice about using the pelts of dead animals in his work.

West's Yeezy Season 5 line had its showcase at New York Fashion Week yesterday, and Sia tweeted a video to West that broke down the cruelty and horror of the machinations of the fur industry.

The Australian singer - who is a vegan and a supporter of PETA - has been vocal about her support of animal rights in the past - even admonishing Azealia Banks for her recent 'chicken sacrifice' pictures, calling it "the wackest sh*t ever".
