Can Cats Eat Yogurt?

Yes — but only in small amounts and with caution. Plain, unsweetened yogurt is not considered toxic to cats, but many cats are lactose-intolerant and may develop digestive upset after dairy.

Plain yogurt is usually not toxic, but it is not an ideal treat for cats

Most cats can have a tiny lick of plain, unsweetened yogurt without serious harm, but dairy can cause diarrhea, vomiting, or gas because many adult cats do not digest lactose well. Flavored, sweetened, or high-fat yogurts are riskier, and yogurt should never replace a balanced meat-based cat diet.

How urgent is this?

Emergency

Go to the ER now

  • Cat is having trouble breathing, facial swelling, collapse, or repeated vomiting after eating yogurt
  • Cat ate yogurt with other dangerous ingredients such as chocolate, coffee, raisins, macadamia nuts, or significant alcohol
  • Cat is weak, severely lethargic, having tremors, or seizures after eating a yogurt product with unknown ingredients
Urgent

See a vet within 24 hours

  • Cat ate a large amount of yogurt and now has ongoing vomiting, diarrhea, abdominal pain, or marked lethargy
  • Cat ate flavored or sugar-free yogurt and you are not sure what sweeteners or additives were included
  • Cat has pancreatitis, inflammatory bowel disease, diabetes, kidney disease, or a history of food allergy and ate yogurt
  • Kitten ate yogurt and develops digestive upset
Monitor

Watch at home, call if it worsens

  • Cat licked or ate a small amount of plain, unsweetened yogurt and is acting normal
  • Mild temporary gas or soft stool after a tiny amount of yogurt
  • Cat ate plain yogurt as an occasional treat but has no symptoms

How to Safely Feed Yogurt to Your Cat

If you offer yogurt at all, keep it rare and very small. Cats are obligate carnivores, so treats like yogurt should stay occasional and should not displace balanced cat food.

  • Choose only plain, unsweetened yogurt with no chocolate, fruit mix-ins, granola, or artificial sweeteners
  • Start with just a small lick or about 1 teaspoon to see whether your cat develops diarrhea, vomiting, or gas
  • Avoid giving large servings — dairy can cause digestive upset in lactose-intolerant cats
  • Skip yogurt entirely in cats with a sensitive stomach, pancreatitis history, food allergies, or on a prescription diet unless your vet approves it
  • Cat toxicity differs from dogs here: xylitol is a major emergency for dogs, but cats are not known to develop the same xylitol-related hypoglycemia or liver injury; for cats, the bigger concern with yogurt is usually lactose-related stomach upset or other added toxic ingredients

Common Questions

Is yogurt safe for cats?
Plain, unsweetened yogurt is generally not considered toxic to cats in small amounts. However, many adult cats are lactose-intolerant, so even a small serving can cause vomiting, diarrhea, gas, or loose stool.
Can cats eat Greek yogurt?
Plain Greek yogurt may be better tolerated than regular yogurt because it generally contains less lactose, but it is still not necessary for cats and can still cause digestive upset. Offer only a tiny amount, if any.
How much yogurt can a cat eat?
If your cat tolerates it, keep yogurt to a very small treat such as a lick or about 1 teaspoon occasionally. Treats should make up only a small portion of a cat's daily calories, and yogurt should not become a regular part of the diet.
What symptoms can yogurt cause in cats?
The most common problems are gastrointestinal: vomiting, diarrhea, gas, and stomach upset. If the yogurt contains other harmful ingredients, signs can vary depending on what was added, so check the label and call your vet if you are unsure.
Is sugar-free yogurt dangerous for cats?
Sugar-free yogurt is not a good choice. While cats are not known to develop the same xylitol poisoning syndrome seen in dogs, sugar-free products may still contain ingredients that are inappropriate for cats, and the full ingredient list should always be checked. If your cat ate a sugar-free yogurt and you are uncertain about the ingredients, call your vet.
