My experience has always been great at PET Supermarket. They carry brands of food that I haven't been able to get elsewhere for my guinea pig and hamster. Occasionally, they feature pets for adoption from animal care & control. That's how we ended up adopting the sweetest cat in the world! I have never owned a cat before, but the team at PET Supermarket gave me instructions on his care and now we have a happy, healthy, furry baby.
Also--they price match! Even from the internet.
