The witching hour belongs to the Women’s Black Cat Onesie

A broomstick leans against the door, a cauldron bubbles somewhere, and on the windowsill a pair of yellow eyes watches the moon rise. Every witch needs her familiar. This black cat onesie for adults slips its wearer into midnight black fleece with a lilac belly, a long tail that sways with each step and a hood full of attitude: pointed ears lined in lilac, golden eyes, a grey nose and embroidered whiskers. Superstition never looked so inviting. Seven years of bad luck? Not in this house.

A Men’s Black Cat Onesie turns bad luck into good

An adult black cat onesie lands on its feet on any occasion. This onesie costume is warm enough for a doorstep full of trick or treaters, the button front closes in seconds, and the loose cut invites a long stretch on the sofa afterwards. Fancy dress parties, horror film nights or a quiet evening with a real cat on the lap, it purrs through them all. The tail flicks behind on the dance floor and curls up neatly when the credits roll. Let this one cross your path tonight, and keep the luck for yourself.

More cats in the alley

The kids black cat onesie gives a little witch’s helper the same lilac belly. The cat onesie answers in black and white for a duo on the sofa. Bats, pumpkins and skeletons gather in the Halloween onesies collection.

Frequently Asked Questions

They’re made to keep you warm on the sofa through autumn and winter, so yes, they’re cosy. The relaxed fit lets air move around, though, so you won’t get that stuffy feeling you get from tight pyjamas.
Machine wash at 30°C on a gentle cycle. Turn them inside out and pop them in a mesh laundry bag to protect the hood. Skip the tumble dryer and the iron. They air-dry quickly and fluff right back up on their own.
Yes, every onesie we sell is unisex. The roomy cut works for men and women alike, our kids’ styles fit girls and boys just the same, and our baby sizes are cut the same way for everyone. Just check the size chart to find your fit.
