I was wondering if those wild bird seed mixes would be a good addition to a rat or mouse diet? Seems like a variety of different seeds and grains would be good for rodents? Is there a reason why in the sticky about Becky's mix sunflower is mentioned specifically, but not any of the other seeds common in bird food (safflower, millet, cracked corn, etc.)

Please note I'm not suggesting this as a stand alone diet. Just seemed like it might be one more good thing to throw in to the mix.
