Ingredients Analysis

The first ingredient is salmon, an oily marine and freshwater fish not only high in protein but also omega-3 fatty acids, essential oils needed by every cat to sustain life.

The second 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 third ingredient is lentils. Lentils are a quality source of carbohydrates.  Plus (like all legumes) they’re rich in natural fiber.

However, lentils contain about 25% protein, a factor that must be considered when judging the actual meat content of this cat food.

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

The fifth ingredient is sweet potatoSweet potatoes are a gluten-free source of complex carbohydrates in cat food. They are naturally rich in dietary fiber and beta carotene.

The sixth ingredient is blueberries. Blueberries are a good source of vitamins, minerals and dietary fiber.

The seventh ingredient is salmon oilSalmon oil is naturally rich in the prized EPA and DHA type of omega-3 fatty acids. These two high quality fats boast the highest bio-availability to cats and humans. 

Depending on its level of freshness and purity, salmon oil should be considered a commendable addition.

The eighth ingredient is salt (also known as sodium chloride). Salt is a common additive in many cat foods. That’s because sodium is a necessary mineral for all animals – including humans.  

Salt can often be found in cat foods to promote cats to drink more water too. This is a means of increasing their hydration and diluting their urine which helps to reduce the likelihood of urinary stones forming.

However, since the actual amount of salt added to this recipe isn’t disclosed on the list of ingredients, it’s impossible to judge the nutritional value of this item.

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.

Nutrient Analysis

Based on its ingredients alone, Health Extension SuperBites Freeze-Dried Raw Salmon recipe looks like an above-average freeze-dried raw product.

The dashboard displays a dry matter protein reading of 38.5%, a fat level of 21.4% and an estimated carbohydrate level of 32.1%.

As a group, the brand features an average protein content of 36% and a mean fat level of 21.4%. Together these figures suggest a carbohydrate content of 34.6% for the overall product line, alongside a fat to protein ratio of 60%.

This means the Health Extension Freeze-Dried Raw range contains near-average protein, near-average carbohydrate and above-average fat, when compared to typical freeze-dried raw cat food.

Health Extension uses only ethical and sustainable means to source high-quality ingredients which is evident in the freeze-dried raw range.
