How much plain yogurt for your cat?
Most guides say "a few pieces". Enter your cat's weight and get the actual daily ceiling, worked out from plain yogurt's calories and the 10%-of-daily-calories treat rule vets use.
Assumes a healthy, neutered adult at a stable weight, and that this is their only treat that day. Puppies, pregnant, very active or unwell pets need different amounts — ask your vet.
Why this verdict for cats
A small amount of plain yogurt is usually tolerated better than milk, but keep it occasional.
Plain, unsweetened yogurt can be a healthy little treat for many pets — its probiotics may support digestion, and it's a handy way to hide a pill. The keys are 'plain' and 'small,' because dairy doesn't suit every pet.
How much is safe?
A spoonful of plain, unsweetened yogurt is plenty. Choose one with no added sugar and, crucially, no xylitol (some 'light' or flavored yogurts contain this sweetener, which is toxic to dogs). Greek yogurt is lower in lactose and often better tolerated.
What happens if a cat eats too much?
Many dogs and most adult cats are somewhat lactose-intolerant, so too much yogurt can cause gas, loose stool, or an upset stomach. Full-fat versions also add calories. If your pet gets gassy or loose, skip the dairy.
How to serve it safely
Offer a spoonful of plain yogurt on its own, stirred into food, or frozen in an ice-cube tray. Always check the label for xylitol and added sugar first.
