Can cats eat yoghurt?
A teaspoon of plain, unsweetened natural yoghurt is fine for most cats now and then — the cultures break down part of the lactose. Sweetened or flavoured yoghurt is off limits.
Why yoghurt for cats?
Yoghurt sits somewhat better with cats than milk: the lactic acid bacteria have already broken down part of the lactose during fermentation. A small spoon of plain natural yoghurt is therefore tolerated by many cats and is sometimes even used to hide medication. It remains a treat without nutritional necessity, though.
How much is okay?
A teaspoon at most, once or twice a week. Yoghurt should never be a fixed part of the ration — it contributes calories without covering feline nutritional needs.
How to feed it?
Only plain, unsweetened natural yoghurt without additives. Off limits are fruit, vanilla and sweetened yoghurts, anything containing chocolate, and above all products with the sweetener xylitol. Greek yoghurt is fine in tiny amounts but has more fat.
Risks & caution
Cats sensitive to lactose can react to yoghurt too — with diarrhoea and flatulence. Sweetened varieties add sugar the cat cannot use; xylitol-sweetened ones are dangerous. Overweight cats should skip yoghurt entirely.
Can kittens have yoghurt?
For kittens, yoghurt is unnecessary and risky — their digestion is sensitive, and diarrhoea dehydrates young animals quickly. Leave it out.
Signs of intolerance
Watch for diarrhoea, soft stools or belly rumbling after yoghurt. If they appear, your cat belongs to the sensitive ones — skip dairy entirely.

Frequently asked questions
Which yoghurt may cats eat?
Only plain, unsweetened natural yoghurt without additives — a teaspoon at most, occasionally.
Why is yoghurt better tolerated than milk?
The lactic acid cultures have already broken down part of the lactose during fermentation, so there is less left to upset the gut.
Is fruit yoghurt allowed?
No. It contains sugar, often additives, and sometimes sweeteners — a product sweetened with xylitol would be outright dangerous.
Can I hide medication in yoghurt?
For cats that tolerate it, a small dab works well as a medication carrier. Test tolerance with a tiny amount first.
Can kittens eat yoghurt?
Better not. Kitten digestion is sensitive, and diarrhoea is quickly dangerous for young animals.
