So you're asking us to believe that it was a congenital disorder of some sort that runs in the family, and not the 'roids...? Hmmm.. how convenient...
The kitteh committed suicide whilst transitioning to Tom Cat status. The owner said that sHe (Grumpy Cat) would become simultaneously confused
and aroused when viewing itself in any reflective surface. Additionally, the cat's family was historically predisposed to species dysmorphia and on more than a few occasions found the cat passed out in front of the TV with "Lassie" playing on loop, wearing a collar that said "Fido" and an old copy of "Pethouse" magazine in it's lap.
Entertainment Tonight also reported (via anonymous sources) that the cat was still despondent over being passed up for a recurring role on "Game of Thrones" having been beaten out by a human midgie for the role of "Tyrion" (Grumpy cat suffered from feline dwarfism).
All these factors coupled with a heavy addiction to Catnip made for what amounts to a hell on Earf for the much loved feline who was found slumped over what had been a "four fingered" bag of Catnip and a half eaten weeks supply of Fancy Feast still clutching a sealed letter marked for delivery to Peter Dinklage in her left paw...Sad....So freakin' sad.
'n' sheit.
