Cats can have pup cups (whipped cream treats from Starbucks), but they are not recommended as a healthy or regular treat. Pup cups contain dairy (lactose), sugar, and additives that most adult cats cannot properly digest due to lactose intolerance. This can lead to digestive issues such as upset stomach, diarrhea, vomiting, and lethargy. Although pup cups are not toxic to cats, they provide no nutritional benefit and can contribute to weight gain and other health problems if given frequently. If given at all, it should be only in very small amounts and very occasionally, while carefully monitoring the cat for any adverse reactions. Healthier alternatives include commercial cat treats or specially formulated cat milk products that are lactose-free.
