Cats can have pup cups (also called Puppuccinos), which are small servings of whipped cream typically served to dogs at Starbucks, but they are not recommended as a regular treat. Pup cups are not toxic to cats, but most adult cats are lactose intolerant and may have trouble digesting dairy products like whipped cream. Consuming pup cups can potentially cause digestive upset, including vomiting, diarrhea, and stomach discomfort. Additionally, whipped cream contains sugar and additives that provide no nutritional benefit to cats and may lead to weight gain or other health issues if consumed often. If given, pup cups should only be offered in very small amounts occasionally, monitoring the cat for adverse reactions. Better, cat-friendly treat alternatives include specially formulated cat treats, small pieces of plain cooked meat, or lactose-free cat milk products. In summary, cats can have pup cups but only as an occasional very small treat, and it's safer to opt for healthier alternatives to avoid digestive and health problems.
