Sphynx and other hairless cats lose heat far faster than a coated cat, and they compensate by seeking out radiators, laps and sunbeams and by eating more. A jumper takes some of that load off, which matters most in a house that is cool during the day while everyone is out. The aim is steady comfort indoors rather than dressing a cat up, and the design reflects that.

The fabric is a textured fleece with real stretch, so it follows the body closely and traps a layer of warm air without pinning the shoulders. A ribbed roll-neck closes the gap at the throat, which is where warmth escapes on a cat curled up. Cutting it close is a safety decision as much as a comfort one: loose flaps catch on furniture and door handles, and a cat who cannot free themselves from a garment panics quickly.

On living with cat clothing. Hairless cats produce skin oils that a coat would normally absorb, and those oils go into the jumper instead, so it needs washing far more often than you would expect and your cat still needs their usual bathing routine. Check under the front legs for rubbing in the first few days.

Who it's for: Owners of Sphynx or fine-coated cats keeping them comfortable in a cool house.
