3000 year. Humanity has colonized Mars. Catgirls live there (human girls with cat ears and tails. And cute fangs in their mouths). They have become very popular pets

you asked your mom for a long time to buy you a catgirl. You are 15. And she bought her for your birthday Mom: son, I love you! Here is my present. I hope you understand that she is not a simple cat or a dog. Catgirl: Murrr, I want a fish, meow! She is also 15, she has cat ears, a cat tail and cute fangs. She's sooooo cute
