All about this product

Product description

Some pet clothing is bought for warmth and some purely for the pleasure of it, and a proper little shirt belongs firmly in the second category. This one is flannel, cut with a turn-down collar and a button-front placket, tailored to sit neatly on a cat or a small dog rather than hanging like a bag. It photographs well, which is usually the honest reason anyone buys one, and it is comfortable enough to leave on for an afternoon.

Flannel is a sensible choice for this sort of thing because it is soft against a coat and holds a little warmth without any bulk, so it works as an extra layer on a mild-but-brisk day when a padded coat would be too much. The tailored cut keeps the fabric close to the body, which matters for a cat: loose clothing catches on things and unnerves them, while something fitted tends to be tolerated far better. Sizes run from XS through to 3XL.

  • Flannel plaid fabric
  • Turn-down collar and button-front placket
  • Tailored cut for cats and small dogs
  • A light extra layer for mild cold
  • Sizes XS to 3XL
  • Buttons at the front for easy fitting

On colour and fit. Fit follows chest girth and back length, not the pet's weight; if you are between sizes on a deep-chested dog, take the larger. It is a shirt rather than a coat, so it is not warmth for a cold walk.

Who it's for: Owners of cats and small dogs who enjoy dressing them up a little, and want something smart that is comfortable to wear.

Why we chose it

Bought for the pleasure of it rather than for warmth, and there is nothing wrong with that. Flannel is the sensible fabric though: soft against a coat, a little warmth without bulk, and cut close so a cat tolerates it.

— Matt, founder
