Ingredients Analysis

The first ingredient is chicken.  Chicken is considered “the clean combination of flesh and skin derived from the parts or whole carcasses of chicken”. 1

Chicken is naturally rich in the 11 essential amino acids required by a cat to sustain life.

The second ingredient is chicken liver.  This is an organ meat sourced from a named animal and thus considered a beneficial component.

The third ingredient is chicken broth.  Broths are of only modest nutritional value. Yet because they add both flavor and moisture to a cat food, they are a common component in many wet products.

The fourth ingredient is carrots.  Carrots are rich in beta-carotene, minerals and dietary fiber.

The fifth ingredient is brown rice flour, a gluten-free substitute for wheat flour.

The sixth ingredient is natural ​​flavor.  Natural flavors doesn’t give us much information about the particular ingredients included in this cat food for flavoring purposes.  

We’re pleased that the flavorings used are natural, but more details are required to give any further information about these natural flavoring ingredients. Flavorings are used to make the foods more appealing and tasty for our cats.

The seventh ingredient is flaxseed oil,  one of the best non-fish sources of omega-3 fatty acids — essential to a cat’s health.

The eighth ingredient is guar gum, a gelling or thickening agent found in many wet pet foods. Refined from dehusked guar beans, guar gum can add a notable amount of dietary fiber to any product gum.

From here the list goes on to include a number of other items. But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of the product.

Recipe star rating 4.

Has Diamond cat food been recalled in the past?

Yes, Diamond Pet Foods has had recalls in the past.

The most recent was in March 2013, when they recalled Diamond Naturals cat food due to potentially low levels of thiamine. 

In April and May 2012, there was a large recall of Diamond and Diamond Naturals, plus several other brands.  Samples of Diamond’s own pet food tested positive for salmonella, which then prompted other brands produced at Diamond’s plant in Gaston, South Carolina, to be recalled including Taste of the Wild and Natural Balance.

In October 2009, Diamond Pet Food recalled two of its cat food brands after cats were reported to have shown neurological symptoms.  The foods affected were: Premium Edge Finicky Adult Cat and Premium Edge Hairball Cat with codes of RAF0501A22X (18-lb. bag), RAF0501A2X (6-lb. bag), RAH0501A22X (18-lb. bag) and RAH0501A2X (6-lb. bag).

In December 2005, Diamond Maintenance and Diamond Professional was recalled following a string of pet deaths and illnesses linked to dog and cat food produced in Diamond’s South Carolina plant. 

The food was thought to be contaminated with aflatoxin, a toxic byproduct of a mold that attacks corn under certain temperature and moisture conditions.
