Kim Kardashian's white Persian cat named Mercy has died. The reality star took to her official blog on Friday, December 7, to inform fans that the 4-month-old cat passed away recently as the result of a "rare stomach cancer," but did not give a specific date.

"It is with deep sadness that I have to tell you all that my kitten, Mercy, has passed away. My heart is completely broken," she wrote.

Kardashian received the cat as a gift from boyfriend Kanye West in September. The cat was named after the first single from Kanye West's new album, "Cruel Summer."

Kardashian revealed in the blog post that she was allergic to the cat and although she kept it for a few weeks, she could not continue caring for the cat as a result of her allergies and gave the cat to her sister Khloe Kardashian Odom's assistant.

"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 [for allergies], and it wasn't fair on Mercy, because I couldn't play with her or give her as much attention as I wanted to," Kardashian wrote. "Mercy deserved a mom who could really give her the time and affection she deserved."

"I knew that Sydney, Khloe's assistant, who had recently lost a cat she had loved and cared for for 17 years, would be the perfect mom for Mercy and Sydney was so excited to have Mercy as her own," she added.

The 32-year-old reality star wrote that Sydney "gave Mercy a loving home, but 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."

"Her [Mercy] stomach had filled with fluid and the doctor said she had a rare stomach cancer and that there was nothing we could do for her," she added. "Poor little Mercy died the very next day. It broke not only my heart that little Mercy died at only four months old, but Sydney's too."

Kardashian last made headlines when it was revealed that West had been deposed in the divorce case against Kardashian's estranged husband Kris Humphries. The two are still nowhere near reaching a divorce settlement. Kardashian filed for divorce in October 2011 after 72 days of marriage.
