Three-month-old kittens cannot drink yogurt. The gastrointestinal development of 3-month-old kittens is not very complete. It is not recommended to eat anything other than cat food, cat rice, and canned cat food. It can easily lead to diarrhea, vomiting, and physical health problems. ​​​​​​

Moreover, yogurt needs to be stored at low temperature, and most of it is cold, which is more irritating to the cat’s gastrointestinal tract and makes diarrhea more likely. Yogurt helps digestion and facilitates bowel movement, which is a burden on kittens' intestines and stomach.
