PETSMART

PETsMART doesn't just cater to animals. It also cares for them. By working with local animal shelters, the pet-supplies chain has found homes for more than 1 million animals through its in-store adoption centers.

Before leaving the store, you can get your new pet professionally groomed, stock up on food, pick out a bed or even a house, and get that little darlin' something squeaky to chew on.

You can even buy your pet a friend with fur, fins or feathers. PETsSMART is truly a one-stop critter shop.
