I am curious if anyone knows any chain stores that either sell or can order the Mazuri rat food. Every feed store that I have called says they can only order llama and small pig mazuri food for some reason. The rat block at petsmart is like $8 for a 2 lb bag so that's out of the question. I'm in west Texas if that helps as far as location for the stores. Also, the 25 lb bag on the Mazuri site looks like it has a significantly greater amount of crude protein (23% instead of 16% and other add ins). It is more expensive than the 6f but if it is all that I can find, is it just as good as the 6f for my small colony? Any suggestions would be greatly appreciated!
