The short answer

A teaspoon of plain, unsweetened yogurt is fine for most cats. Fermentation lowers its lactose content, so it's better tolerated than milk. Check the label carefully, though: flavoured and 'light' yogurts often contain sugar, fruit or artificial sweeteners, and some contain xylitol. Stick to plain full-fat or Greek yogurt, and stop if your cat gets loose stools.

Why the verdict

Bacterial cultures break down some of the lactose in milk, so many lactose-sensitive cats can tolerate small amounts. It's still dairy fat and protein that cats don't need. Xylitol is a well-known danger for dogs; data in cats are limited, but it's widely advised to avoid it. Fruit flavourings may include grape or raisin.

How to prepare it

  • Plain, unsweetened, unflavoured only.
  • Check for xylitol and other sweeteners.
  • No fruit-on-the-bottom, vanilla or chocolate varieties.
  • Start with half a teaspoon.
Kittens: Not necessary. A lick is okay.

Signs of trouble

  • Diarrhoea
  • Gas or bloating
  • Vomiting
When to call the vet: If vomiting or diarrhoea lasts more than 24 hours, or your cat is lethargic, stops eating or seems in pain. ASPCA Poison Control: (888) 426-4435.
