I think I've seen articles here and there about concern with P'lets in particular and pellets, you may want to look into that. I can't recall exactly since I don't have a p'let but I usually try to skim facts on all species (but we all know that nothing about diet related is fact!! You're probably aware of what I'm talking about Jim since you're up on diet related stuff for the fids).
