Anyone who shares their home with a cat knows the drill. You open a container of yogurt, and before long, a furry head appears, sniffing and pawing. Cats seem fascinated by dairy products. But curiosity aside, many pet owners ask: can cats eat yogurt safely?
The short answer: yes, but only in moderation and with the right type of yogurt. Not every yogurt is safe, and even safe yogurt should be treated as an occasional snack, not a dietary staple.
In this detailed guide, we’ll break down the science of cats and yogurt—covering the health benefits, potential risks, safe serving sizes, and expert opinions.
Do Cats Like Yogurt?
Cats are naturally curious about the smell and texture of dairy foods. Yogurt has a tangy aroma and creamy consistency that can attract them. However, cats don’t crave yogurt for taste in the same way humans do. Cats are obligate carnivores and lack taste receptors for sweetness.
According to Cornell University’s College of Veterinary Medicine, cats respond more to fat and protein than sugar, which explains why they sometimes try to lick yogurt.
Can Cats Eat Yogurt Safely?
Yes, but with caution. Plain, unsweetened yogurt—particularly Greek yogurt—is the safest option. Small amounts are unlikely to harm a healthy adult cat. Yogurt contains probiotics, protein, and calcium, which may benefit cats in limited doses.
But flavored or sweetened yogurts pose risks. Many contain added sugars, artificial sweeteners (like xylitol, which is toxic to pets), and fruit blends that may upset a cat’s digestive system.
The American Society for the Prevention of Cruelty to Animals (ASPCA) warns against giving cats any dairy products that include additives, artificial sweeteners, or chocolate.
Lactose Intolerance and Cats
Most adult cats are lactose intolerant. This means they lack the enzyme lactase, which breaks down lactose (milk sugar). Without lactase, lactose ferments in the digestive system, leading to bloating, gas, and diarrhea.
Interestingly, yogurt is often easier for cats to tolerate than milk. The live cultures in yogurt break down some of the lactose, reducing digestive discomfort.
Still, tolerance varies by cat. Some may enjoy small amounts without issues, while others experience stomach upset even from a spoonful.
The PetMD veterinary resource emphasizes that while yogurt is less risky than milk, lactose intolerance remains a concern for most cats.
Health Benefits of Yogurt for Cats
When served responsibly, yogurt can provide certain benefits:
- Probiotics
Yogurt contains live bacteria cultures that may support gut health. Probiotics can aid digestion and promote a healthy microbiome. - Protein
Yogurt is rich in protein, which cats require for muscle maintenance and energy. - Calcium
Calcium supports bone strength, teeth health, and nerve function in cats. - Hydration
Yogurt has a high water content, which can
Risks of Feeding Yogurt to Cats
While yogurt can offer probiotics and protein, it also carries risks:
- Digestive Upset – Many cats are lactose intolerant. Even with live cultures, too much yogurt may cause bloating, diarrhea, or vomiting.
- Added Sugars and Flavors – Fruit yogurts, vanilla blends, and chocolate-flavored varieties often contain harmful ingredients. Xylitol, sometimes used as a sweetener, is toxic for cats.
- Caloric Impact – Yogurt adds extra calories that can contribute to weight gain, especially for indoor cats with low activity levels.
The ASPCA warns pet owners that many human dairy products include unsafe additives.
How Much Yogurt Can Cats Eat?
Moderation is essential. A small teaspoon of plain, unsweetened yogurt once or twice a week is enough. Anything beyond that increases the chance of stomach upset. Yogurt should never replace meals or be considered a staple.
PetMD notes that occasional human food treats can enrich a pet’s life but should make up no more than 10% of daily caloric intake.
Safe Yogurt Types for Cats
Not all yogurt is created equal. The safest choices include:
- Plain Greek yogurt – thick, protein-rich, lower in sugar.
- Natural unsweetened yogurt – with no flavorings or sweeteners.
- Live culture yogurt – supports gut flora more effectively.
Unsafe options to avoid:
- Fruit-blended yogurts
- Artificially sweetened yogurts
- Yogurts with toppings like granola or chocolate
The Humane Society urges pet owners to avoid sweeteners like xylitol, which can be fatal to cats even in small amounts.
Alternatives to Yogurt
If your cat cannot tolerate yogurt—or if you’d rather not risk it—consider these alternatives:
- Veterinary probiotic supplements designed for cats
- Fermented goat’s milk (pet-safe brands)
- Cat treats fortified with probiotics
- Prescription digestive diets recommended by veterinarians

Signs of Yogurt Intolerance in Cats
Always observe your cat after giving yogurt. Warning signs include:
- Loose stools or diarrhea
- Vomiting shortly after eating
- Gas and bloating
- Lethargy or lack of appetite
If these occur, stop feeding yogurt and contact your vet.
The American Veterinary Medical Association highlights that persistent gastrointestinal symptoms may indicate food intolerance or underlying conditions.
Can Kittens Eat Yogurt?
Kittens should not eat yogurt. Though they produce more lactase as babies, their digestive systems are fragile and easily disrupted. Proper kitten formula and balanced growth diets are far safer than experimenting with dairy.
International Cat Care stresses that kittens thrive best on diets designed for growth and development, not human foods.
Myths and Facts About Cats and Yogurt
| Myth | Fact |
|---|---|
| Cats love dairy, so yogurt must be safe. | Many cats enjoy the smell of dairy but cannot digest lactose well. |
| Yogurt can cure digestive problems. | Only prescribed probiotics or vet care can reliably treat gut issues. |
| Cats need yogurt for calcium. | A balanced cat diet already provides sufficient calcium. |
Final Thought: Should You Give Cats Yogurt?
So, can cats eat yogurt? Yes—if it’s plain, unsweetened, and given in very small amounts. Yogurt is not toxic, but it’s unnecessary and can cause stomach upset in lactose-intolerant cats. For digestive health, safer alternatives exist, like vet-approved probiotics.
Your cat’s diet should remain meat-based, with yogurt as an occasional indulgence rather than a routine snack. If in doubt, consult your vet before adding new foods.
