One time my baby sitter told me this, she made it up and it was kind of cheesy so I made my own version of it.

One day there was an evil old lady who had a heart as cold as ice. She had an old cat who was just as mean and cold hearted as she was. When he was mad [which was ALL the time] he ripped up all the furniture with his very sharp claws. The little old lady got so sick and tired of that that she stabbed him with her pocket knife. She cut off his head and his claws so he couldn't ever scratch again. No, No, wait. that doesn't make sense. If he's dead he can't claw otherwise. actually, when he was sleeping Old Lady Cut off his paws, and he died from blood loss anyway. she threw him in the garbage and opened the window and went to sleep.

meanwhile, The cat in the garbage was slowly mutating into something big...hairy....and bloody.... so, when he mutated 100%, he went and jumped through the open window of his former mistress's home and slowly climbed on her bed. he hopped on her chest, and slowly started licking very rapidly where her heart was, and then biting, and pretty soon was at her heart. He ripped it out of her chest and ate it piece by cold piece. he ripped all her old organs out and pretty soon all there was left was a bloody, torn flesh corpse sitting on an extremly bloody bed. Some people have triied to move into that house, but for some reason hear sounds, like a tiger roaring a flesh ripping. old ladies screaming..... veins snapping.... AND, TO THIS DAY, HIS BROTHER STILL ROAMS YOUR NEIGHBORHOOD. OOOHHH..... HE'S RIGHT.. BEHIND....YOU.......AHHHHHH!!!!
