Kim Kardashian has been left heart broken after her beloved cat, Mercy, passed away earlier this week, with the reality star uploading an obituary for her feline friend on to her official website in order to detail her heartbreak.

Fans of Kim will know the kitten from the numerous pictures that she uploaded to her Twitter account featuring herself and the cat, or just Mercy on its own, and may very well be just as torn up about the passing as Kim is. Mercy was just four months old.

In her post on her official website, Kim first explains the Sophies Choice-like scenario she found herself in when she first met Mercy, discovering that she was allergic to cats, but had fallen head over heels in love with the kitten that she just had to put her troubles behind her and succumb to taking injections to making living with the kitten an option. She goes on to explain in her heart-wrenching farewell; "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, and it wasn’t fair on Mercy, because I couldn’t play with her or give her as much attention as I wanted to."

She goes on to explain that Mercy had developed a stomach problem, which resulted in the cat's stomach filling with liquid. A day after it's diagnosis, the kitten passed away.
