"Before police could break down the door to her bedroom where she had barricaded herself, Hello Kitty took her own life using her custom pink Remington Model 1100 shotgun. Hello Kitty was pronounced dead on the morning of August 30th 2003 at 12:52 am."
A random game of Google Image Search led me to this charming series, The 9 Tragic Suicides of Hello Kitty, by Los Angeles artist Thom Foolery. All the classic self-obliteration methods are included: from hanging, to drowning, to everybody's favourite -- electrocution! Each "suicide" scene is supported by a detailed account of poor Hello Kitty's demise.
It would have been nice to have seen Death by Stereo included here, but alas, kitties only have but 9 lives.
