Pet Supplies Plus is located on E M21 in Owosso. They are in a shopping plaza next to a Family Dollar, Goodwill, etc. What I like best about them is that you can bring your pet inside the store with you. We have ran into a lot of little cuties while shopping there. They have a large selection of supplies, helpful staff and reasonable prices. If your into fish, you can even pick out your own fish...sort of like self-serve! The only downfall I would say is the cleanliness of the store.
