With four dogs, three cats, and a bird, I am quite a frequent customer at our local Petsmart. They have exactly what I need, and so much more.
No matter what your pet - dog, cat, bird, turtle, fish, hamster, or even a horse... this store has products for all. And if you get a free "PetPerks" card, you can save money on many of your purchases, and earn extra dollars in savings for your next visit!
Inside Petsmart there is a grooming service, training classes, and even a room for the local humane society to feature pets that need homes. You can also bring your pet inside to shop with you, which is great (and often entertaining!).
Also, I must comment on their great staff. They are always pleasant, friendly, and fast in the checkout lane. Many times I get heavy bags of dog food, and there's always someone there to help me load up my car.
Overall, the best place to shop for quality pet supplies in Evansville.
