Circus of Freaks

One day, the Doctor was experimenting at the circus and messed something up, causing it to explode, turning everyone in the circus into cats, and the Doctor into a bird. Harlequin immediately freaked out, saying, "What the hell?! Doctor!" They didn't know what to do or where to go, and with their paws, they were unlikely to be able to turn everything back. Pierrot quietly left. The others noticed and followed him, and along the way, some were touched, saying, "Look, three cats in jester hats, one cat in a top hat, and a bird in a Plague Doctor mask!" They barely made it to Y/N's house. Pierrot rubbed his paw on the door and meowed. Y/N opened the door.
Y/N: Who's there? Stopped at the threshold looking at the cats and Pierrot the bird ?!
Pierrot: Meow, oh yeah.
Y/N: animals talk...
She let them in and said she would try to help them, so that's how they live every day after work. Y/N tries to mix chemicals, as the Doctor says. If Y/N falls asleep, all the cats lie down on her bed, and in the morning they wake up in different places: Pierrot, well, he stayed with Y/N, Jester on the windowsill, the Doctor on the closet, Ticketer in the kitchen, and Harlequin on the table with his face in a glass. Y/N almost always wakes up early from the noise of bowls or meowing. They refuse to eat food on principle, only meat, and they speak humanly, which often scares Y/N.

Pierrot:
A white cat with yellow eyes and a red jester's hat on his head. He loves Y/N and gets sad if he doesn't pay attention to him.
Harlequin:
A black cat with green eyes and a green jester's hat, constantly trying to scratch Y/N, and it's him who makes noise with his bowl at night, "let me eat."
Jester:
Purple cat, of these idiots, he's the main one and the most adequate... almost, purple jester's hat, purple eyes, doesn't like being petted, but wants attention, and then, like a businessman, he leaves
Ticket:
a black and white cat with a blue top hat, also more or less adequate
Doctor:
A black bird, wearing a Plague Doctor mask, turquoise eyes, he tells Y/N what chemicals to mix after work
Y/N:
The girl has fair skin, gray eyes, black hair, and works as a waitress in a cafe.
