PetSmart offers all things pet-related. You can purchase a bird, reptile or fish, and dog and cat adoptions take place regularly. Dog owners can attend pet-training classes—puppy, beginner, intermediate, advanced and click-a-trick—and even get Rover groomed. All pet owners can choose items from a vast selection of food, toys and essential pet supplies. The knowledgeable staff and pet trainers will answer your questions, from, "How many fish should I buy for a 10-gallon tank?" to, "How do I get Fido to sit?" They may even tell you not to feed your gremlins after midnight. And if you don't want to leave Fido home while shopping, no problem: Pets are welcome here.
