Most cats and dogs are lactose-intolerant to some degree, but some might be able to enjoy a small portion of whipped cream occasionally. Also, Starbucks whipped cream usually contains vanilla syrup, which could be toxic to some pets. If you are removing the whipped cream from your own beverage to feed to a pet, bear in mind that it also could have small amounts of coffee, tea, chocolate, sugar-substitute, or other animal-toxic ingredients from the drink.
