As a cat owner (Maine Coon - a "doglike cat") I've been noticing an increase in the inclusion of peas & other legumes in the market over the last couple of years. I believe that boutique pet food makers have been using it because it's a cheaper source of protein than even chicken by-products. One cat food I saw listed tapioca as the 2nd ingredient[1]. WTF - that's a starch, what is it doing in food for a carnivore? But it came in really good looking packaging, though. So far she has done well on the bulk packs of canned Friskies and Fancy Feast (both Purina products) from Costco. [1] Packaging laws say ingredients have to be listed in decreasing proportion.
