I need some help. What is the difference between oat groats and oatmeal? Also are oat hulls a filler and what is their purpose in pet food? Which is better oatmeal or oat groats-or are they both equally as good? Also what is pearled barley vs. barley? Is their a difference between the quality of these ingredients? And is millet a seed or a grain? Please explain throughly, thanks!

Groats and oatmeal come from the same plant, however groats have had the husk removed; oatmeal has not. I suspect that the food you're looking at uses oat hulls as a source of mostly insoluble (non-digestable) fiber, so they are sort of a filler (something having little to no nutritional value) and sort of not. Similarly, pearled barely has had the husk removed and the grains have been polished, so barley would retain the husk and thus have some additional benefit for fiber. Millet is actually a plant, but the tiny spherical components of the plant that are used in foods are actually seeds and not grains.
