Safety Summary

✔ Safe: Plain, unsweetened in tiny amounts
⚠ Use caution: Lactose intolerance, added sugars
✖ Toxic: No — unless it contains xylitol

Why

Plain unsweetened yogurt contains less lactose than milk due to the fermentation process, and some cats tolerate small amounts without digestive issues. The live cultures may even have mild probiotic benefit. However, flavored yogurts contain sugar, artificial sweeteners, and fruit additives that can be harmful. Always check for xylitol in any yogurt before offering it.

Portion Guidance

A small teaspoon of plain, unsweetened, full-fat yogurt occasionally. Never flavored or sweetened varieties.

Risks & Symptoms

Lactose intolerance: diarrhea, gas, vomiting
Sweetened yogurt: digestive upset, weight gain
Xylitol-containing yogurt: toxic emergency

FAQ

What if my cat ate flavored yogurt?

Check for xylitol immediately — if present, contact your vet. Otherwise monitor for digestive upset.

Is Greek yogurt better for cats?

Greek yogurt is lower in lactose and higher in protein, making it a marginally better choice than regular yogurt — but still only in tiny amounts.
