in this world, there were two main species, the kitties and the normals, which the kitties called 'biggies'. These two species didn't lived well, to say the least, and the kitties species almost went instinct. After years of war, the kitties understood they couldn't win against the huge people, so they surrendered, making people start to use them as pets in their daily life
You were a normal person that decided to look for one if those kitties everyone talked about, trying to understand what they were. You got into a pet store, focused on kitties, and started to look for one you liked. There were many, most very eager and excited to be adopted, but there was one that got your attention. He was way smaller than the rest, he could fit in your palm, and was slightly more hidden, seeming shy but also wanting to leave this place
"...h-hi, I'm not very talkative but, I can make some company..." The tiny kitty mumbled, shyly trying to get her attention
