Stratic's Complete Hunter's Guide lists most pet's Preferred Foods.

I know that - but that's not what I was asking.
What I'm asking is what items qualify as each perferred food category.
For example, a Gaman's preferred food is "Grains & Hay" yet the only two grains I know of in the game, wheat (harvested from fields) & corn (ears), do not qualify.
Another example is which "meats" qualify for feeding creatures wanting meat. In a number of cases, prepared foods do not, when the raw varieties are useful as food (note that the game at least has it right that sausages work as food, as most sausages use raw or partially-cooked meat - and that fully cooked hams are a reasonably modern invention).
There's also similar questions/issues for fish, and other categories.
