Kim Kardashian’s kitten Mercy has died after only four months on this planet.

Kim Kardashian, 32, received the adorable white Persian kitty from her rapper boyfriend Kanye West last September, but was unable to care for it herself after discovering she was allergic.

“I had fallen SO in love with Mercy that I wanted to try everything I could to keep her, but I didn’t think it was safe to resort to injections,” Kim Kardashian told her 16.7 million followers Friday.

On October 16, Kim Kardashian passed along the responsibility of the furry feline to her sister Khloe’s assistant Sydney Hitchcock, who had lost her own cat after 17 years.

Kim Kardashian continued: “After a couple of weeks Mercy got really sick and Sydney had to rush her to the vet. They discovered she had a stomach problem that we weren’t aware of. Poor little Mercy died the very next day.”

According to E! News, Sydney Hitchcock got a call from her boyfriend saying the feline was “limp and not moving” on November 26, and the next day they had Mercy euthanized.

Unfortunately, the fatal, cancer-like virus attacked Mercy’s tiny stomach and Kim Kardashian was reportedly quick to point the finger at the breeder.

“Kim is really upset,” a source told E! News.

“She was upset about Mercy dying and upset that she was trying to do something nice for Sydney and then she fell into a situation where [Sydney] had to grieve another kitty. Kim called the breeder and said they should be more responsible.”

Kim Kardashian had always dreamed of owning a kitten and named Mercy after one of Kanye West’s songs.

“My heart is completely broken,” Kim Kardashian said on herofficial blog.

“Mercy was a gentle and loving kitten and we are all going to miss her so much. Thanks to Sydney for making Mercy’s short life one filled with love. RIP Mercy Xo.”
