With age, most cats become sensitive to lactose in milk and its derivatives, and are unable to digest it well. At about 12 weeks of age, cats stop producing the enzyme needed to digest them, and their diet changes to become fully carnivorous.
For this reason, many adult cats suffer from lactose allergy, and if ingested, they often become victims of digestive disorders (vomiting, diarrhea, gases, etc.), so if your cat vomits or develops diarrhea regularly, it may be due to The milk or “bad” yogurt you eat.
In comparison to other dairy products (cheese, cream, butter …), yogurt is the least bad of them, because it contains good bacteria that are believed to aid digestion, and therefore, regular yogurt may be easier to digest than other dairy products for your cat.
If she is not allergic to lactose, she can take it in very small quantities (1 teaspoon). But only occasionally and exceptionally. On the other hand, if there is any sign of a problem with her digestive system, she will finally stop giving her yogurt.
What about flavored yogurt ?
If there is food, you should avoid giving it to your cat, as it is sweetened or flavored yogurt (with fruit or vanilla, for example). It contains a lot of sugar, artificial sweeteners and preservatives. These substances are very harmful to the health of cats.
In fact, cats do not have the amylase necessary to digest sugar. In addition, she does not have the necessary sensors in her mouths to reveal sweet taste, so giving sugar to cats in any way is dangerous for them and completely useless.
