At least this was my impression of this project. Reviews.com decided to find out which is the best cat food and so they set out to disqualify brands on various pretenses. Now, some of this makes sense, but honestly some criteria are just too strict IMO. They end up disqualifying respectable brands that are frequently recommended by TCS members here, and IMHO their reasons are not always valid.
At least some of the ingredients in their "controversial ingredients" list are not known to be unsafe for cats, by any means. And no, studies in mice are pretty meaningless without addressing quantities. Anything can be toxic, even water, it's all a question of how much of it you feed, considering feline physiology. Some things can be toxic to mice in certain concentration but perfectly safe to feed in moderation to cats (or humans for that matter), and vice versa too. Some things can be safe to feed to mice, even in large quantities, yet entirely toxic to cats even in small amounts. In short, I'm not thrilled with their list of "controversial" ingredients, when the so-called "controversy" is often sparked by companies with a vested interest in selling people unnecessary supplements.
Also, recalls are not necessarily a bad thing. A large company is bound to have more recalls than a smaller company, especially if the smaller company doesn't adhere to the same quality assurance standards. So many brands were taken off their list for that, it's mindboggling.
Still, I think at least they seem to have done a fair job of sorting out through the data, so this is an interesting article to read. Just with a grain of salt, is my suggestion. I'd love to hear more from TCS members on this.
