Plain unsweetened yogurt is safer than milk, and a small spoonful is usually okay.

Why it’s a sometimes-food

Live-culture yogurt contains less lactose than milk, and the bacteria pre-digest some of it, so many cats tolerate a small amount better. It still delivers dairy sugar and fat, and flavored yogurts bring sugar, fruit and sometimes xylitol — those are off the table.

How to serve it safely

Offer a teaspoon of plain, unsweetened yogurt with live cultures occasionally, and stop if loose stools appear.

Warning signs to watch for

Loose stools, gas or vomiting in lactose-sensitive cats within a day.

When to call the vet

Never feed yogurt sweetened with xylitol; if one was eaten, contact a vet immediately.

Common questions

Does yogurt help a cat’s digestion?

Marketing says yes; feline evidence is weak. Probiotic supplements made for cats are a better-supported option.
