You know what? Pets are smart. They know that you have catnip at the bottom of the shopping bag. They know when you’ve switched out their usual treats for those “low-calorie” ones. And they seem to have a sixth sense about when you’re going to PetSmart. There’s a general feeling of giddiness when they know that you will soon return with toys, bones, food, a bed and anything else that can bring joy to our furry friends. So be just as smart as your pets and shop at PetSmart.
