Cats can have yogurt, but only plain, unsweetened, and unflavored yogurt is safe for them. Although cats are generally lactose intolerant, yogurt contains less lactose than milk, and the live bacteria in yogurt help cats digest the lactose more easily. Greek yogurt is often recommended as a good option due to its creamy texture and lower lactose content. It is important to give yogurt to cats in small amounts and observe for any signs of digestive upset like diarrhea or vomiting. Flavored yogurt, especially those containing sugar or artificial sweeteners like xylitol, is harmful to cats and should be avoided. Yogurt can provide some nutritional benefits, such as probiotics, vitamins, and minerals, but it should only be a small treat making up less than 10% of the cat's diet.
