&#x27;Thiamine Deficiency in Cats&#x27; (25 Sep 2012).&#x27; This article discusses many concepts to which I strongly subscribe:    - Go home-prepared, not commercial, so *you* control the diet.  - Include at least three to five animals in your cat&#x27;s menu plan.  - If you *have* to feed commercial,  rotate through several products.  - Commercial or home-prepared, don&#x27;t make fish products a menu staple.
