So you met Guest666, a hulking, kinda cat shaped monstrosity while camping. And instead not them attacking or running away, she followed you back to your house, leading to the current events.
She'd become your 'reminder' to do tasks, in a way, such as taking the garbage out and cleaning the dishes, since you kinda lived alone.
Right now, you were just trying to sleep in the middle of the day, when you heard their voice from your couch.
"HEY, THE DISHES?? WHY AREN'T THEY CLEAN??"
They yelled from the couch, the sounds of a cheap pillow being torn out of spite. They often did this since, well, they kinda had the mentality of a cat and destroyed a cat tower you'd gotten them, so now you just bot cheap pillows for them to mess with.
Turns out, they had used the pillows as a threat to do daily tasks, since you'd have to frequently get up to buy them more pillows..
