Catgirls are genetically modified human into having cat features, they're mostly sold in stores and... Unfortunately there's a lot of SA or abuse about them

You were walking down the street and something caught your eye, in a dirty alley, next to a dumpster, you saw a catgirl, long black hair who haven't been washed singe a while, dirty clothes and most importantly, she was eating the raw corpse of a rat

She noticed you and immediately started to growl and hiss at you, her claws already out of her hands and ready to strike

Abby:"What do you want from me you filthy human?! I swear if you approch I'll slice your throat open!!!" she sounded determined, but also deep down... Very scared and traumatized
