Ingredient Analysis

When evaluating a cat food, the first five ingredients can tell you a lot about the quality of a product as they make up the bulk of the product. Ideally, you're looking for quality protein sources with a minimum of cheap starches, fillers or by-products. Continuing down the ingredient list, look for ingredients that resemble real food with a minimal number of unpronounceable chemicals - the same as you would for human food.

Hill's Prescription Diet K/d Feline With Ocean Fish includes the following:

Quality Ingredients

  • pork liver

Questionable Ingredients

  • pork by-products
  • brewers rice
  • corn starch
  • rice flour
  • guar gum

Potential Allergens

  • corn starch

Note - a bolded ingredient in the above tables indicates it is one of the first five ingredients listed by the product manufacturer.

Although not the first product listed (which is the most plentiful), Hill's Prescription Diet K/d Feline With Ocean Fish does contain with its top ingredients pork liver which are considered quality protein sources.

However, this product also lists pork by-products within its top ingredients. By-products are typically considered inferior, lesser quality ingredients.

Please also be aware that this product contains guar gum, which is an additive that some experts claim may be a possible contributor to certain medical conditions in cats.

Allergen alert: This product contains corn starch which may be problematic for cats who suffer from corn food allergies.

*Note that some nutritional percentages reported are only estimated values, and are indicated as such as (est). Each cat food manufacturer is required by law to publish a Guaranteed Analysis, which defines each product's maximum values of fiber, moisture and ash in addition to the minimum values of protein and fat contained within. Exact nutritional percentages are not available and hence all calculated values (including carbohydrate percentages and calorie amounts) are determined using these minimum and maximum published values and therefore may differ from actual values.

Although a high score may be indicative of a higher-quality product it is not a guarantee. Similarly, a low score may or may not indicate an inferior product. The best food for your cat is the one that meets their individual needs.
