You should try to find a local breeder. Prices and quality should both be better whether its for breeders or what you feed till you get going. I'm southeast of Louisville, so not too far from Lexington and I have too many rats right now and if you wanted to come to Taylorsville, I could hook you up.
There are probably breeders in lexington if you could figure out where they are. There is a Facebook page (Louisville Reptile Classifieds) or (Kentuckiana Reptile Trader) and you could post on those to maybe find someone closer.
