Are there any food mixes at Petco or Petsmart that will work for a flying squirrel?

I'm wondering if there are any food mixes at Petco or Petsmart whether they be for chinchillas or other small mammals that will work for flying squirrels? It would be a lot easier if I could go to my local pet store than having to order mixes from online.

I have feed a wild bird seed called "Nut & Berry" that you can get from Walmart or Lowes
to some of the flying squirrels along with fresh vegetables and they did wonderful.
