Worth it or not?

I am looking for a small mammal...have wanted a ferret for years...I've been stalking Satomi's ferret posts and am aware that a raw diet seems to be the way to go...wondering if it can be that epigen 90 kibble with whatever raw thrown in interrmittently...as a pure raw diet isnt feasible right off the get go for me.

Also wondering if there are any good websites/books I can do some research through?

Thanks
