Oh don't mind me Semerrell. I thought you had posted the pic of YOUR baby and it was in the post by Uni.
Here is a great formula for SFS. They take it as a baby and continue to take it as adults also. Many adult flyers love their FoxValley. The diet of SFS is very complex in captivity. They need a diet rich in calcium to prevent Metabolic Bone Disease and also protein.

They use the 32/40 because it has a higher protein content that the other FV for squirrels. SFS need more protein than other squirrels. They are omnivores ... they eat plant material and bugs and worms.
I think the reptile habitat will be OK temporarily but the shoe box will definitely NOT be good. If it is a tiny baby a plastic Sterilite container with fleece and of course holes cut into it will be OK. If it is a little older it will chew through a shoe box before you can say, "Where did it go?"
You really need something secure until you are bonded. If the baby gets loose in your house now there is a good chance that you will never find him. It would be like finding a mouse in your house. I'm sure PetSuperMarket has some bird cages that will be good starter cages. The most important thing is bar spacing. They should not be larger than 1/2 inch.
