It might sound like a commercial, but PetSmart is the first name that comes to mind when I think of getting something for my cat. He only gets the best, which means I have to go to a [usually pricier] specialty store to find his food.
I particularly like this location. Fairly easy to get in and out of, though other places in this parking lot can be more difficult to get to. I always get a parking spot up close. Like all locations, they're huge inside. Probably half of the store is dedicated to cat and dog food. Unlike other locations, they've stuck all of their fish, bird and reptile stuff in the back. They know the money is with the cat and dog business. Cat adoption is up front, though it's not quite spring so not many kittens there. Dog training and grooming is right up front.
Things are pricey. My cat's Science Diet is $30+ for the big bag. They have a sort of card program called Pet Perks which gives random discounts from time to time on different things. Doesn't seem to have any rhyme or reason to me, but I take what I can get. Staff was super friendly and helpful. Checkout can definitely be a bit slow sometimes.
