4. My view, as in the human food industry, the profit motive is stronger than the caring motive

- from the comments section the article;

"Someone stated that only the pet companies “care” enough to do the studies. Clinical studies are very expensive, and pet companies have the money to do it. They also have a profit motive to sell these products and sponsor the classes and seminars. Pet nutrition research should be from independent sources, not companies that have a profit motive. Would you want Kellogg’s or Frito-Lay funding research on pediatric nutrition?"
