Hairless and thin-coated cats feel a cold house in a way that a moggy with a dense double coat simply does not. A Sphynx will hunt out radiators, sit on laptops and refuse to settle in a draughty room, and an older cat losing condition often does the same. A layer that traps their own body warmth against them solves that quietly, without you having to heat an entire house to suit one animal.

The fabric is a soft two-tone plush with a fluffy inner face, and the warmth comes from the air held in that pile rather than from anything electrical. It pulls on over the body and fastens closed, and the cut is deliberately loose through the shoulders and belly so a cat can still stretch out, crouch, wash and use a litter tray without the coat pulling. Five sizes run from XS to XL in a single fuchsia colourway.

• Soft plush outer with a fluffy insulating inner face
• Pull-on body fit with a secure fastening
• Cut to allow stretching, crouching and grooming
• Sizes XS, S, M, L and XL
• One colourway only, fuchsia
• Weight between 120g and 160g depending on size

Two things worth knowing. Cats are far less predictable about clothing than dogs; some settle into a coat within minutes and some freeze on the spot and refuse to walk. Try it indoors first and take it off if your cat stays unhappy. And the warmth is reflected body heat, not a heat source, so a cat who is genuinely unwell or very underweight needs a warm room as well.

Who it's for: Owners of Sphynx, Devon Rex, thin-coated or elderly cats who visibly seek out heat in a cool home.
