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.

Doctors Foster & Smith Signature Series Adult Lite Cat Food includes the following:

Quality Ingredients

  • chicken
  • chicken meal
  • herring meal
  • chicken liver

Questionable Ingredients

  • whole brown rice
  • brewers rice
  • corn protein concentrate

Potential Allergens

  • herring meal
  • corn protein concentrate
  • dried egg product
  • fish oil

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

In this case, Doctors Foster & Smith Signature Series Adult Lite Cat Food's most plentiful ingredient listed is chicken, which is considered a quality protein source. It also contains chicken meal as additional quality protein sources.

Additionally, Doctors Foster & Smith Signature Series Adult Lite Cat Food also contains as top ingredients whole brown rice and brewers rice. These types of ingredients are typically used as bulk-adding fillers and are not required in your cat's diet. However, they are sometimes used to help maintain the kibble shape in dry foods.

Allergen alert: This product contains herring meal, fish oil, corn protein concentrate and dried egg product which may be problematic for cats who suffer from seafood, corn or eggs 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.
