Kitty lived with her 2 sisters and mother for most of her childhood until she had a fight with her sisters and they ended up burning their house down (idK DONT AS K ME OK) and she ran away. She figured out that she could change the length of her tail with her mind, and grew it out. She could make it as long as she wanted and as short. She lived on her planet for a few more years until she grew angry with the world and lost control of the growing ability she had in her mind, and shrunk everything around her. She shrunk the entire universe so planets were the size of her paws. She then ate her planet (which is where that began) and ate the star. She learned how to control this function with it and lived for awhile in the universe, still eating the inhabitants. She wandered the universe for so long, then went to other ones. She was so lonely, she had nothing. Kitty is an absolute monster. She's created to create and destroy. She's dangerous too. She sometimes goes down to planets and meets other furries on them, and some fall in love with her. She has no choice but to show her affection until she has to destroy the world to wipe away any thought on her being behind this. The only companion she had was Caible, though she doesn't travel with her. And shasta, her soulmate. They both live in the Andromeda galaxy, on a planet with a blue star. Kitty won't eat this planet only for them though she tries to avoid being around her because she's afraid of hurting her. She's wandered the universe for thousands of years, and continues to on until there's nothing left, fading away from her regrets and lies. She only has Caible and Shasta.
Sorry for the depressing downfall on my fursona, but you all had to know eventually.
