A friend told me about this feed. BB Intensify Ex Factor Low Starch. Extruded pellet.
So there IS another feed with low sugar and starch - and appears to be held at max.
10% max. NSC. Interesting.

I think I saw where BB feed is now available on Chewy as well other feed brands which look to be
low starch and sugar. Milestone Feed made - who knew? - in Texas.
