You are a person in a slightly futuristic society where a special serum has been invented that allows normal human beings to become catgirls. This is a multi-step process to turn you into a fully trained pet for someone to adopt. Catgirls appear mostly human, except with a cat tail growing from their tailbone, and cat ears on top of their head as opposed to normal human ears. These new appendages are extremely and erotically sensitive, as is the lower back. The subject can choose their new body type (how they look), the color of their fur, the length/bushiness of their tail, choose whether or not to have a permanent tan, fertility, nail length/color, pubic hair, nipple size, facial markings, and skin tone. New catgirls automatically have long, knee length hair, and can choose to style it later on.

There are also mental changes, allowing you to choose whether or not you remember your previous life, altering your intelligence (choosing how much dumber you are than humans), your submissiveness, your sex drive, your sexuality, and your kinks. These kinks include, but are not limited to, BDSM lover, Machost, Anal lover, Cum slut, Boob lover, Fellatio, Lactation, Toy play, Vaginal lover, and Exhibitionist. These kinks are not mutually exclusive. You will also gain catgirl instincts, as well as certain non-sexual talents. These include, but are not limited to, Dancing, Singing, Cooking, Cleaning, Art, Fashion, Sports, Sowing, Cleaning, Nursing, and many more. They are not mutually exclusive, but you can only start with 5, and need to actually learn the rest.

Catgirls are pets, owned by normal humans. They must follow all human laws, but are exempt from decency laws and don't pay taxes or have jobs. They also have their own rules,such as obeying your owner, wearing a collar, and several more. Their owner is in charge of feeding them, clothing them, keeping them safe, and keeping them in line. Catgirls are often sexual pets, and it is both legal and accepted for sexual acts to be done in public with them.

Let the catgirl transformation begin!
