Review of Hill's Science Diet Adult Hairball Control
Ocean Fish 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 Adult Hairball Control Ocean Fish Entree provides complete and balanced nutrition for the maintenance of adult cats.
We'll begin this review of Hill's Science Diet Adult Hairball Control Ocean Fish Entree with a detailed discussion of the ingredients.
The first ingredient is water. Water of course only provides moisture, a necessary component of wet cat foods.
The second 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 third ingredient is ocean fish. Ocean fish can refer to multiple species of fish, since the particular type of fish is not specified, it's difficult to discuss this ingredient. The nutritional contribution of ocean fish depends on the species included; however, fish generally provides high quality protein and fat.
The fourth 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 fifth ingredient is 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.
Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Science Diet Adult Hairball Control Ocean Fish 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 chicken fat. Chicken fat is typically collected while cooking chicken using a process called rendering. Chicken fat is a relatively high quality source of essential fatty acids. In particular, chicken fat is high in linoleic acid, an important omega-6 fatty acid.
The next ingredient is wheat flour. Wheat flour is produced by grinding uncooked wheat into a powder. In addition to dietary fiber, wheat flour provides various vitamins, minerals, and plant based protein.
Wheat is considered a controversial ingredient because of it's protein content. Plant based proteins degrade the overall protein quality in the product. In addition, many people believe wheat is one of the most common ingredients to cause food allergies or intolerance. However, grains such as wheat are typically low offenders in comparison to certain protein sources such as beef.
Then we have corn starch. Corn starch is derived from the endosperm of the corn kernel. Typically, corn starch is used as a binder in kibble.
Moving on, we have whole grain corn. Whole grain corn is the entire corn kernel (the germ, bran, and endosperm). Corn is a 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.
Moving on with this review, we have natural chicken liver flavor. As the name implies, natural chicken liver flavor provides chicken liver flavor to the product. This particular flavor is derived from natural sources which may or may not include real chicken liver.
The next ingredient in this review is calcium sulfate. Calcium sulfate is a food additive that helps control acidity levels and functions as a firming agent. It's not a desirable ingredient, but it is considered safe by the FDA in small quantities.
Our next ingredient is natural flavor. Natural flavor enhances the flavor of the product. The difference between natural and artificial flavoring is that natural flavoring starts from a plant or animal whereas artificial flavoring is entirely man-made.
The remaining ingredients in this Hill's Science Diet Adult Hairball Control recipe are unlikely to affect the overall rating of the product.
Our analysis of the ingredients show that this product derives most of its protein from animal based sources. This is an excellent property because meat based protein contains all of the necessary amino acids required by cats. In our option, this is one of the most important properties to judge when reviewing pet food, therefore we believe this is an exceptional product in this regard.
In summary, we recognize that this product contains anonymous meat ingredients. These are not necessarily always negative; however, they are typically low quality and inexpensive additions. If the particular anonymous meat ingredient is controversial or low quality, it should have been discussed earlier in this review. Otherwise, it is safe to assume the anonymous meat ingredient is an acceptable addition.
