Cats can drink whole milk, but it's not recommended for kittens. Many kittens experience indigestion and other allergic reactions after drinking whole milk, such as constantly licking or biting their paws, or rubbing their faces on the floor, indicating skin irritation and itching.
Even if a cat doesn't get diarrhea from drinking milk, it should still be given fresh water afterward. In addition, milk taken from the refrigerator can sometimes cause diarrhea in cats due to the cold stimulus, so the food given to cats should not be too cold. In cold weather, you can slightly heat the food first.
