Kim Kardashian's kitten Mercy dies

Washington, Dec 8 (ANI): Kim Kardashian is mourning the death of her pet kitten 'Mercy', which was a gift from her boyfriend Kanye West.

According to the E! News, the TV personality, who gave away her adorable pet to sister Khloe's assistant Sydney after discovering she was allergic, is very sad after the fluffy feline passed away from a "cancer-like virus often associated with breeding," Us magazine reported.

"Kim is so sad [about losing Mercy]," the publication quoted a source, close to the reality star, as saying.

Mercy's new owner, whose own cat had passed away after 12 years at that time, decided to have her euthanized after learning that her kitten was terminally ill, and that "even aggressive treatment" wouldn't help her situation.

Kardashian first showed off the newest Kardashian on Instagram in early September. She named her pet after one of boyfriend West's summer hits, "Mercy." (ANI)
