Example Input: It makes good tasting gluten free food... but... like most gluten free food, it's expensive and it's got a slight grit to it. I've made biscuits, waffles, and pancakes with it... a friend made some awesome banana bread with it. it's very good for gluten free...

Example Input: This slop has the color and consistency of baby diarrhea with whole peas in it. Our cat ate less than half a bowl of this slop and immediately puked all over the carpet!  She devours the Felidae Platinum, (which we feed as an occasional alternative to Newman's Own Turkey). She was raised on Felidae dry, so I can say that generally the Canidae Company provides quality products... except for this grain-free slop. You can find the good stuff at: <a href="http://www.amazon.com/gp/product/B000WFL09S">Felidae Canned Cat Food for Senior and Overweight Cats, Platinum Diet Formula (Pack of 12 13 Ounce Cans)</a>  Absolutely do not order this slop from Amazon because they will charge you $10.70 for the privilege of returning the 11 cans your cat will not eat. Before you make the same stupid mistake I did, buy a can from your local pet food store and try it out first. Then, when your cat pukes this slop back up, you will only be out $1.59 instead of the $27.94 Amazon nailed me.  In my opinion, your cat and you will be much better off with Newman's Own Organic cat food, especially the turkey and chicken. The Newman food literally brought our cat back from the brink of death! After we listened to our former vet and fed her Science Diet K/D, she dropped down to less than 4 pounds in a month. We switched her back to Newman's Own Turkey and within one 24-case of small cans she was back up to her usual weight of 6.2lbs, and has maintained that healthy weight for over 6 months. She also gained increased mobility after we stopped feeding her the K/D. I read somewhere that Science Diet buys veterinary students their books in exchange for their later recommendations of their products. Nice.  Just say NO to Science Diet and Felidae Grain Free Formula. Here's the good stuff: <a href="http://www.amazon.com/gp/product/B000VK8HJ0">Newman's Own Organics Turkey & Vegetable Formula for Cats, 5.5-Ounce Cans (Pack of 24)</a>  (Did they really want me to post a video with this review? Would you? Then its unanimous, this review will remain video-free!)
