Cats can generally drink a little yogurt without any problem, but every cat's digestive system is different. Before feeding it yogurt, it's best to give it a tiny bit first to see if its stomach can handle it. 
Yogurt tastes great, its tangy flavor is very appetizing, and it's a good idea to give your cat some yogurt to stimulate their appetite in hot weather. However, be careful not to give your cat too much yogurt at once, otherwise it can easily cause diarrhea.
Yogurt can promote intestinal peristalsis and aid digestion, relieving indigestion in cats. For cats suffering from constipation, consuming yogurt in moderation can also help relieve constipation.
