Liver & Chicken Entree
This product is manufactured by Hill's Pet Nutrition, Inc..
According to our data, this Hill's Science Diet recipe provides complete & balanced nutrition for the maintenance of adult cats. In other words, this formula is AAFCO approved.
Unlike other AAFCO approved cat foods which rely in laboratory testing to substantiate nutritional adequacy, this recipe has undergone feeding trials. In the pet food industry, feeding trials are often considered to be the superior testing method.
Animal feeding tests using AAFCO procedures substantiate that Hill's Science Diet Perfect Weight Adult Liver and Chicken Entree provides complete and balanced nutrition for the maintenance of adult cats.
We'll begin this review of Hill's Science Diet Perfect Weight Adult Liver and Chicken Entree with a detailed discussion of the ingredients.
The first ingredient is chicken broth. Chicken broth provides both flavor and moisture; however, as with other broths, chicken broth does not provide any notable nutritional contribution.
The second ingredient is pork liver. Pork liver is an excellent organ meat which provides high quality protein and fat. In addition, pork liver provides many essential vitamins and minerals.
The third ingredient is pork by-products. By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, pork by-products contain nearly all parts of pork which are typically not consumed by humans. These parts include the liver, lung, spleen, kidney, stomach, blood, intestine, bone, etc.
Like other meat by-products, pork by-products are considered controversial, mainly because they are inexpensive ingredients which consumers have equated with slaughterhouse waste. However, manufactures and many experts claim that animal by-products are unjustly criticized. Proponents state that "named" by-products, such as pork by-products, supply many important nutrients required by cats.
The fourth ingredient is carrot, which are naturally rich in vitamins, minerals, and antioxidant.
The fifth ingredient is corn flour. Corn flour a ground cereal grain which provides a modest amount of vitamins, minerals, and plant based protein. It also happens to be one of the most controversial ingredients in cat food.
Proponents of corn claim that corn is highly digestible and an excellent source of protein, energy, vitamins, minerals, and essential fatty acids.
Opponents however believe that positive claims in regards to corn are either half-truths or completely false, we'll discuss a few of the opposing arguments.
In regards to digestibility, the claims of "highly digestible" are only true if corn is processed into a meal or flour and subsequently cooked. In regards to the protein contribution, we must note that corn is a plant based protein which does not contain all of the necessary amino acids required by cats to sustain life. Therefore substituting corn for meat is an unsuitable substitution and actually degrades the overall protein quality of the product.
Finally, we'll discuss the claims about vitamins and minerals in corn. Although corn does provide many vitamins and minerals, it not necessarily an exceptional ingredient in this regards. There are many other ingredients which are more complete and biologically appropriate. Therefore the usage of corn as the primary ingredient in cat food should certainly warrant further questioning.
Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Science Diet Perfect Weight Adult Liver and Chicken Entree are not as important as the first five ingredients.
However, collectively they still have a significant impact on the overall quality of the product. Therefore, we'll continue discussing the remaining ingredients in this Hill's Science Diet recipe.
Next we have powdered cellulose. Powdered cellulose is produced from minuscule pieces of wood pulp and plant fibers. Other than its fiber content, powdered cellulose lacks any nutritional contribution.
The next ingredient is corn starch. Corn starch is derived from the endosperm of the corn kernel. Typically, corn starch is used as a binder in kibble.
Then we have chicken, which is an excellent source of protein and fat.
Moving on, we have flaxseed. Flaxseeds are an outstanding source of omega-3 fatty acids and dietary fiber. They also provide a notable amount of protein, B vitamins, and various minerals.
Moving on with this review, we have dried tomato pomace. Dried tomato pomace is a by-product of tomato manufacturing. It's considered a controversial ingredient because many people believe it is an inexpensive low quality filler. However, tomato pomace provides a notable amount of dietary fiber, B vitamins, Lycopene, and vitamin A. Although it is a very inexpensive ingredient, it is not nutritionally empty.
The next ingredient in this review is spinach. Spinach is an edible flowering plant which supplies a notable amount of dietary fiber and plant based protein. It's also naturally rich in vitamin A, vitamin C, vitamin K, magnesium, manganese, and folate.
The remaining ingredients in this Hill's Science Diet Perfect Weight Adult recipe are unlikely to affect the overall rating of the product.
Our analysis of the ingredients show that this product derives a considerable amount of protein from non-meat ingredients. This is an undesirable property because plant based protein often lacks many of the necessary amino acids required by cats. This property is typically found in lower quality products.
In summary, we recognize that this product does not contain any artificial colors, artificial preservatives, or anonymous meat ingredients.
