Does this store sell feeder mice or rats?

Yes I believe they do but to double-check give them a call before you go to the store.

I am not sure,suggest you call the store first. RuthB

Yes

I know they have feeder gold fish, but I am not as sure about the feeder mice... If they don't, I would try the PetSmart on Watt. Petco also has smaller supply shops that only carry dog and cat supplies, so I am only certain about the fish at the Arden store.
