Possibly getting a hedgie...

I have been thinking of getting a hedgie but i am not sure yet.

What should i know about them before getting them?

Cage? Would a ferret nation or critter nation work? If not, what cage is the best?

Toys? Best toys for them? Where to get them? Can i make my own?

Food? Where can i get it? Best brands?

Animals? Can they play with other animals, like chinchillas?

List of supplies i need to get before getting one.

Pros and Cons?
