Slim, short-haired cats and small dogs sit against radiators for a reason, and a knitted layer does much the same job while following them around the house. Cable knit is the traditional choice for it because the twisted stitch pattern is thicker than plain knitting, trapping more air in the same weight of yarn. A ribbed collar and cuffs hold the shape and stop the whole thing riding up over the shoulders after ten minutes.

It pulls over the head with the two front legs through the openings, which is the simplest design to get onto an animal who is not enthusiastic about being dressed, and the stretch in the knit means it moves with them rather than pinning the shoulders down. Light enough to wear indoors without overheating, it suits draughty houses, elderly pets and the ones who genuinely shiver. Two colourways are offered, a navy braided rope and a grey twist, in sizes XS to XL.

Knitwear and claws. A loose knit catches on claws, so this suits a supervised pet rather than one left alone in it all day, and a cat who is genuinely unhappy in clothing will freeze in place rather than object politely; if yours stops moving, take it off.

Who it's for: Short-haired cats and small dogs in cold houses, especially older pets who no longer hold their own heat well.
