It's disheartening that so many are "prescribed" that junk when more healthy alternatives are out there. Even if they're eating crunchy stuff with all the nutrients cooked to death and rendered useless, it should at least be NATURAL ingredients.
Who the heck ever decided that eating the cellulose from pine trees was natural for beast and man? I seriously doubt any entomologist is going to tell us that the termite's natural diet is what's best for those of us with 2 and 4 legs.
