Yogurt is known for its health benefits in humans, but is it safe for cats? Yes, cats can eat yogurt, but only in moderation. While yogurt is packed with nutrients and probiotics that benefit humans, it’s not a staple food for your feline friend. The good news is that the live bacteria in yogurt help break down lactose, making it easier for most cats to digest than milk.
Stick to plain, unsweetened yogurt without any added flavors, sugars, or sweeteners. Ingredients like xylitol, often found in flavored or “light” yogurts, are toxic to cats. Offer just a small spoonful occasionally and monitor for any signs of stomach upset. Used sparingly, yogurt can be a safe and tasty treat—but your cat’s main nutrition should still come from a balanced cat food diet.
Let’s dive deeper into our research on cats and yogurt.
Can Cats Eat Yogurt?
More than 65% of adult cats are lactose intolerant, meaning their digestive systems struggle to break down lactose—the natural sugar found in milk. However, yogurt is different. During fermentation, beneficial bacteria such as Lactobacillus bulgaricus and Streptococcus thermophilus convert much of the lactose into lactic acid. This process makes yogurt easier to digest than milk for most cats.
Still, not every cat tolerates dairy well. Some may experience diarrhea, gas, bloating, or vomiting within 8–12 hours of eating it. For that reason, yogurt should be offered only in small amounts and occasionally, while keeping an eye out for any signs of discomfort.
Health Benefits of Yogurt for Cats
When given in small amounts, plain yogurt can offer several nutritional benefits for cats. Here’s a look at what makes this treat potentially helpful:
Nutrient / Component | Role in Cats | Yogurt Benefits | Extra Notes / Tips |
Vitamin B12 | Supports red blood cell formation, digestion, and nervous system | Helps prevent anemia, supports energy levels | Important for senior cats; deficiency can cause lethargy and neurological issues |
Vitamin D | Maintains bone and muscle health, aids calcium absorption | Contributes to strong bones and healthy teeth | Cats synthesize little vitamin D from sunlight; dietary sources matter |
Protein | Provides energy, supports muscles, organs, and skin | Yogurt adds a small, digestible protein boost | Cats are obligate carnivores; yogurt protein is supplemental only |
Probiotics (Lactobacillus, Streptococcus) | Supports gut flora balance, improves digestion, boosts immunity | Can help prevent diarrhea, constipation, and hairballs | Some cats may be more responsive than others; start with tiny amounts |
Calcium | Builds strong bones, teeth, supports muscle and nerve function | Yogurt is a digestible source of calcium | Works best with phosphorus for skeletal health; avoid overfeeding |
Phosphorus | Supports bones, teeth, and energy metabolism | Present in yogurt in moderate amounts | Important to maintain Ca:P ratio; excess can harm kidneys |
Vitamin B2 (Riboflavin) | Converts food into energy, supports skin, coat, and eyes | Helps maintain a healthy metabolism | Works together with other B vitamins; deficiency is rare in cats on balanced diet |
Magnesium | Supports nerve, heart, and muscle function | Found in trace amounts in yogurt | Helps prevent urinary tract issues; monitor overall dietary intake |
Zinc | Supports skin, coat, and immune function | Present in small amounts in dairy | Essential for wound healing and healthy fur |
Potassium | Maintains fluid balance and muscle function | Small amounts in yogurt | Important for heart and kidney health; mostly covered by primary diet |
While yogurt can add small nutritional perks, remember—it should complement your cat’s diet, not replace their regular, balanced cat food.
Potential Risks of Yogurt for Cats
While a small spoonful of plain yogurt is usually safe for most cats, there are several risks to keep in mind before sharing.
Lactose Intolerance
Many adult cats can’t properly digest dairy because their bodies produce little or no lactase, the enzyme needed to break down lactose (milk sugar). Although yogurt contains less lactose than milk, it can still cause mild digestive issues such as gas, bloating, or loose stools—especially in sensitive cats. Always start with a tiny amount and watch how your cat reacts.
Excess Sugar
Most commercial yogurts contain added sugars, which provide no nutritional benefit for cats. Since cats can’t taste sweetness, sugar only adds empty calories and increases the risk of obesity, diabetes, and dental problems. Always choose plain, unsweetened yogurt if you plan to share a small portion.
Toxic Ingredients
Flavored or sweetened yogurts may contain harmful additives. , an artificial sweetener, is highly toxic to cats and can cause a dangerous drop in blood sugar and even liver damage. Other ingredients sometimes found in flavored yogurts—such as chocolate, grapes or raisins, citrus, and coconut—can also upset your cat’s stomach or lead to poisoning. To stay safe, stick to plain, unsweetened yogurt only, and offer it sparingly as an occasional treat.
Can Kittens Eat Yogurt?
Kittens can usually tolerate small amounts of yogurt while they’re still nursing because their bodies produce lactase, the enzyme needed to digest lactose. However, after weaning, their lactase levels naturally drop, making it harder for them to process dairy products.
For that reason, it’s best to avoid giving yogurt to kittens and stick to kitten formula or veterinarian-approved food designed to support their rapid growth and delicate digestive systems. These provide all the nutrients kittens need without the risk of stomach upset or nutrient imbalance.
What Types of Yogurt Are Safe for Cats?
Cats can safely enjoy only plain, unsweetened, and unflavored yogurt. The best option is plain Greek yogurt, which is thicker, creamier, and typically lower in lactose than regular yogurt—making it easier on your cat’s stomach. Its rich texture is also appealing to many cats.
Avoid flavored yogurts such as vanilla or fruit varieties, as well as any containing chocolate or sweeteners. Ingredients like xylitol, a common artificial sweetener, are toxic to cats and should always be avoided.
Before offering yogurt, read the ingredient label carefully to ensure it contains only milk and live bacterial cultures—nothing more.
How to Safely Introduce Yogurt to Your Cat
Before sharing yogurt with your cat, remember the 10% rule for treats: all snacks—including yogurt—should make up no more than 10% of your cat’s daily calorie intake. The remaining 90% should come from a balanced, species-appropriate diet that provides all essential nutrients.
When introducing yogurt, always choose plain, unsweetened, and unflavored varieties. Flavored or sweetened yogurts often contain additives that can be harmful to cats. Start small—no more than one teaspoon, once or twice a week—and never let your cat lick directly from your cup or container, as this can lead to overeating.
After offering yogurt, monitor your cat closely for any signs of digestive upset, such as diarrhea, vomiting, bloating, or lethargy. These symptoms may appear within a few hours and can indicate lactose intolerance or sensitivity.
Finally, avoid giving yogurt to kittens. Their developing digestive systems are sensitive, and they should receive nutrition exclusively from kitten formula or veterinarian-approved food, not dairy products.
Alternatives to Yogurt for Cats
Alternative | Benefits | Notes |
Cat-safe probiotics | Supports gut health, digestion, hairballs, gums | Formulated for cats; lower in calories |
Lactose-free milk | Easier to digest than regular milk | Offer occasionally; not a staple |
Fermented foods | Source of probiotics | Consult vet before introducing; not all are safe |
While small amounts of plain yogurt are generally safe, there are healthier alternatives to support your cat’s digestion and gut health:
Cat-Safe Probiotics
Instead of relying on yogurt for probiotics, consider supplements formulated specifically for cats. These products provide beneficial bacteria without harmful ingredients, are lower in calories, and may help with hairballs, digestive health, and gum care.
Lactose-Free Milk Products
Lactose-free cat milk contains added lactase enzymes to help break down lactose, making it easier for cats to digest. It can be offered occasionally as a treat, but should not replace a balanced diet.
Fermented Foods for Cats
Fermented foods are another source of probiotics. Some options include milk kefir, pickled carrots, or small amounts of sauerkraut. Always consult your veterinarian before introducing any fermented foods, as not all are safe for cats.
Conclusion
So, can cats eat yogurt? They can enjoy small amounts of plain, unsweetened yogurt, but it should only be offered occasionally and in moderation. Yogurt can provide probiotics, protein, calcium, and vitamins, supporting digestion and overall health. However, because many cats are lactose intolerant, even yogurt can cause digestive upset in some pets.
Always avoid flavored or sweetened yogurts containing harmful ingredients like xylitol, chocolate, or fruit additives. Kittens and sensitive cats should skip yogurt entirely, relying instead on kitten formula or balanced cat food.
For a safer, more controlled way to support your cat’s gut health, consider cat-specific probiotics, lactose-free milk, or veterinarian-approved fermented foods.
Ultimately, yogurt can be a safe, occasional treat, but your cat’s main nutrition should always come from a complete, species-appropriate diet.
