Cats can drink yogurt. Yogurt is made from milk through fermentation, which breaks down the proteins and lactose that are difficult to digest and absorb, while retaining most of the nutrients. Therefore, it won't cause diarrhea in cats. Adult cats can drink yogurt in moderation, but kittens should not drink it because their digestive systems are not fully developed. Yogurt contains probiotics, which can help promote digestion in cats. It offers certain benefits to cats. Owners can also choose pet-grade yogurt for their cats, which has a lower sugar content and reduces the risk of oral diseases. 
Cat Dietary Considerations:
1. The vitamins and trace elements in cat food are very important for cats, as they promote growth, aid digestion, fight disease, maintain healthy skin, and keep their fur smooth.
2. It is not recommended to frequently supplement cats with calcium, because large amounts of calcium cannot be digested and may eventually lead to urinary tract stones, gallstones, etc.
3. Fat is also a major source of calories for cats. Pet owners must pay attention to controlling their cats' fat intake and can occasionally feed them some foods rich in fat.
4. Set a fixed time and place for feeding each day. Do not go early or late. Adult cats should generally be fed twice a day.
