When I first started out, I was very concerned about their diet.  I mean look at Americans and how we eat!

I got off to a good start and continued fine-tuning it from there:

This is Kaytee Fiesta Mix.  

A bit high in protein and fat but a great assortment of items makes it a healthy and colorful addition.

This is Kaytee Supreme.

This makes up a larger portion of the grain that I provide to them because of the stable base of "nuggets".

Both of these are obtained from my local Petco from a Bulk bin which I always inspect visually and with my nose!

These are good ol' Lab Blocks.  I obtain these at a local shop.  They are made by Teklad, type 8640.

Rats don't always like these or will eat them recluctantly but these ensure that a rat recieves the specific, required amounts of vitamins he/she needs.

ALL DONE!

Along with the above ingredients, I also add a rotating variety of cereals, dried fruit and rotini pasta to keep their interest.

How my dry Mix looks after it's all done.

I mix small batches at a time to last about 2-3 weeks.
