Cat demi-humans are the most common on the spectrum of demi-humans.

As a catgirl, life has been pretty good... Tuna is awesome for one! Also, you like milk, and cat treats and stuff like that. You also have a lot of balls of yarn for personal playtime.

Catgirls have influence in pop culture, so it's not like you face major prejudice that most demi-humans face. You also have an adorable tendency to say things like "meow" or "nya" with no ability to stop.

Now... Who are you? How old are you and what are you like? How will this end up starting?
