Every cat owner has probably wondered whether sharing a spoonful of yogurt with their curious feline friend is safe. Yogurt is a popular human snack — creamy, flavorful, and packed with nutrients — but what about cats? In this guide, we explain everything you need to know about feeding yogurt to your cat, including its health benefits, potential risks, portioning advice, and expert recommendations.
Can Cats Eat Yogurt? The Short Answer
Yes — cats can eat plain, unsweetened yogurt in small amounts. Not all types are suitable, and some cats may be lactose intolerant.
Understanding Cats and Dairy
Cats are obligate carnivores, meaning their digestive systems are designed primarily for animal-based proteins rather than dairy products. Most adult cats lack enough of the enzyme lactase, which breaks down lactose — the sugar found in milk and dairy. As a result, many cats are lactose intolerant and may experience digestive discomfort when consuming dairy.
Yogurt is different, though. During fermentation, beneficial bacteria break down much of the lactose, making yogurt easier for some cats to digest than milk.
Is Yogurt Good for Cats? Pros and Cons
✅ Potential Benefits
Yogurt isn’t required in a cat’s diet, but a little may offer some benefits:
- Probiotics for digestion: Yogurt contains live cultures (good bacteria) that may support healthy gut function.
- Protein source: Yogurt has protein, which cats need for muscle and body maintenance — though regular cat food already provides sufficient amounts.
- Yogurt has calcium, potassium, and B vitamins, but these are usually in good cat food.
❌ Possible Risks
Despite some benefits, yogurt also comes with drawbacks:
- Lactose intolerance: Even fermented dairy can still contain lactose, meaning some cats may get gas, vomiting, or diarrhea.
- Additives and sweeteners: Many flavored yogurts contain sugar, artificial sweeteners (like xylitol), or flavorings, which can be harmful or toxic.
- Unbalanced nutrition: Yogurt should never replace complete cat food; it’s not formulated to meet all their dietary needs.
What Type of Yogurt Can Cats Eat?
If you decide to give yogurt to your cat, choose the right kind:
✔ Plain, unsweetened yogurt — No sugar, no fruit, no chocolate.
✔ Low-fat or non-fat options — Easier on the stomach.
✔ Greek yogurt — A thicker texture with less lactose.
Avoid:
❌ Flavored yogurts (e.g., vanilla, strawberry)
❌ Yogurts with sugar substitutes
❌ Yogurts with fruit pieces or additives
Important: Never feed your cat yogurt that lists xylitol or other artificial sweeteners on the label, as these can be dangerous.
Can Kittens Eat Yogurt?
No — it’s best not to feed yogurt to kittens. Kittens have developing digestive systems, making them more sensitive to new foods and potential imbalances. They may be more likely to have stomach upset or not get the nutrients they need. Healthy kittens should receive only their mother’s milk or specially formulated kitten food until weaning.
How Much Yogurt Should You Give Your Cat?
Even when you choose a safe yogurt, portion size matters:
- Very small amounts: Only a teaspoon or two at a time is enough as a treat.
- Occasional treats only: Yogurt should not exceed about 10% of daily calories and should remain an infrequent snack.
Too much yogurt may upset your cat’s stomach—start with a small amount and watch for reactions.
Signs to Watch After Feeding Yogurt
Keep an eye out for any signs that your cat isn’t tolerating the yogurt well:
- Diarrhea
- Vomiting
- Gas or bloating
- Refusal to eat
If your cat shows any of these symptoms after eating yogurt, stop immediately and consult your vet.
Vet Tips: When to Give Yogurt to Cats
Before introducing yogurt into your cat’s diet, a quick check-in with your veterinarian can help determine if it’s a good choice for your specific pet. This is especially important if your cat has:
- Digestive issues
- Food sensitivities
- Health conditions like kidney disease
Some vets may recommend cat-specific probiotic supplements, which provide digestive support without the risks associated with dairy.
Final Thoughts: Treat With Caution
In short, cats can eat small amounts of plain, unsweetened yogurt occasionally, but it isn't essential to their diet.
Feed your cat high-quality, species-appropriate cat food for main nutrition. Yogurt should only be an occasional treat. Our veterinarian is the best source of personalized advice for your cat’s diet and health.
