Caring for an adult cat can either be easy or hard. The best way to make the transition from a kitten to an adult cat is to feed it on formulas that are appropriate for its age. Lucky for you, there are quite a good number of adult cat formulas in the market today. The Science Diet Adult Optimal Care Original (dry) is one such formula.
The company that manufactures this formula claims that this is the ultimate formula for your adult cat. It is claimed to contain easy to digest nutrients that make visible differences in your cat. They even go as far as offering a money back guarantee on this product.
The company seems to have a lot of confidence in their product. Is it as good as they say it is?

An overview of the first 5 ingredients
Chicken is a very popular ingredient for pet food and in this case, they are referring to whole chicken. This is a very high quality meat source and we are pleased to see it listed. However, whole chicken loses about 80% of its content during the cooking process since the majority of whole chicken is water. After the cooking process is complete, the amount of whole chicken remaining is substantially reduced. Therefor, while whole chicken is a great source of meat protein, this ingredient alone is not enough to provide sufficient levels of meat protein in a cats diet.
Whole Grain Wheat
Whole grain wheat is a grain based product that may cause some digestion issues. In addition it is also a known food allergen for many cats. Grain based ingredients like this one are usually used by pet food companies because it is a cheap way to boost the protein percentage of the food. That said, it provides almost no nutrition for cats because cats do not have a digestive system designed for plant based proteins or nutrients. They are designed to consume and process meats. While this isn’t a bad ingredient in moderation, in higher quantities, it usually reflects a lower quality cat food.
Corn Gluten Meal
This is the dried residue from corn after the removal of the larger part of the starch and germ, and the separation of the bran by the process employed in the wet milling manufacture of corn starch or syrup, or by enzymatic treatment of the endosperm. The expression “corn gluten” is colloquial jargon that describes corn proteins that are neither gliadin nor glutenin. Only wheat, barley, rye and oat contain true gluten. For the most part, this ingredient is normally only found in cheaper “grocery store brand” cat foods. Corn is frequently used as a filler ingredient to help make your cat feel more full, but it does not add much of anything to the nutritional value in the food. In addition, this is a common allergen for many cats and corn based ingredients can often be difficult for cats to digest. That’s why we can’t recommend this food for cats with food allergies or sensitive digestive systems.
Pork fat is also known as lard, but it doesn’t look as good to put that on the ingredients list! In general this is a good source of fat and we are happy to see a named fat source (as opposed to something generic like “animal fat”). All cats require a healthy fat source. It’s only a problem if they consume too much of it (like humans). When we compare pork fat to other named animal fat sources, there seems to be a higher instance of digestion upset with pork fat. However, in most cases, this is a quality fat source.
Brewers rice is the small milled fragments of rice kernels that have been separated from the larger kernels of milled rice. It is a processed rice product that is missing many of its nutrients, but does provide a source of carbohydrates. It is a by-product of rice milling and considered a lower quality filler ingredient usually used in lower priced cat food blends. Usually, brewers rice is used to make rice flour, but if the quality is too poor for rice flour, it will then be sold to pet food or dairy feed companies. For many cats, this ingredient can cause allergies or digestion issues. Most cats will not have any problems processing this food, but it’s not one of the better ingredients, either.
Other ingredients in the formula
Dried Beet Pulp
Beet pulp is a by-product from the processing of sugar beet and is a source of fiber and energy. It is popular among many pet food companies due to its high availability and low price. The most common complaint about this ingredient is that it causes digestion problems, most commonly a very hard stool or diarrhea. It has also been known to cause bloat in some dogs and cats which can be very serious if left unchecked.
Dried Egg Product
Derived from shell free eggs, this is a cheaper source of protein used in place of higher quality meat proteins. Normally, this ingredient is derived from waste products associated with the egg industry or egg products that have been deemed unfit for human consumption.
Fish oil is a popular supplement used by cat and dog owners. In this case, the food is already supplemented with fish oil. This ingredient is high in very healthy Omega-3 and Omega-6 fatty acids. This can lead to an improved coat, healthier skin, boost to the immune system, lower blood pressure, and help improving cognitive function in older pets. There are also some studies that show fish oil to help assist with certain allergies in dogs and cats. This is a higher quality ingredient.
Dried Apples, Dried Broccoli, Dried Carrots, Dried Cranberries, Dried Peas
Wild cats like lions, tigers, cheetahs, leopards, jaguars, and other big cats in the wild almost always eat the stomach contents of their prey. Ingredients like these are often found. So while cats are obligate carnivores, they are adapt to eating undigested or partially digested fruits and vegetables. In lower quantities, these ingredients can assist with digestion and provide other nutrients.
Can my cat develop allergies from feeding on this formula?
Unfortunately, this formula contains several allergy causing ingredients. It is, therefore, unsuitable for cats with sensitivities to corn, wheat and gluten.
Other harmful ingredients to avoid feeding your cat on
BHA/BHT – Both BHA & BHT are preservatives that have been banned in human foods in many countries due to cancer risks. However, they remain approved for use in pet foods. A growing number of pet owners are becoming aware of the potential dangers these ingredients bring and are shunning all foods containing BHA and BHT. A quick internet search on these preservatives will show that the backlash is gaining steam with many cat food companies abandoning these ingredients. BHA and BHT are extremely controversial ingredients in all forms of pet food.
Added color and flavor – Both artificial and natural flavor ingredients are considered to be lower quality ingredients. Artificial flavor is usually derived from petroleum. Most have not been studied for safety or toxicity. They are all synthesized chemicals that don’t even have common names. Most artificial flavors actually contain many chemical ingredients, not just one. Many of those chemicals are volatile. Both natural and artificial flavors are chemical based ingredients and we don’t get all that excited when we see either one of those ingredients listed. Both of these ingredients have potential allergy risks and other possible health problems in cats. We also find it quite irresponsible to include artificial coloring in pet food since the health concerns about these added colors are so controversial. Your cat does not care what color their food is and the only reason artificial coloring is added to this product is for marketing purposes. It makes the food look better to you YOU, the human consumer. Of course, many cat food brands are very defensive about their use of food coloring. Here is an example of how the Purina brand defends their use of fool coloring. Notice how even in their explanation, there is no perceived benefit to these ingredients other than changing the color. There is also a growing amount of evidence to suggest food coloring may be linked to cancer in not just dogs and cats, but also humans. Here is an article that explains a bit further. In short, since there is some controversy surrounding this ingredient, we find it a bit strange that cat food companies would spend money adding this ingredient into a product when at best, it has zero nutritional value for your cat and only has marketing value. At worse, it could pose health risks. It just doesn’t seem like the risk of including this ingredient is worth it.
Soy – Soy is another common food allergen for cats and is also known to cause gastric upset. This ingredient is considered a very low priced filler ingredient. While it will certainly help make your cat food more full, the full nutritional benefit in this ingredient is questionable at best. Many cat food brands will tell you the allergy risk is very low with soy, but it is one of the most well known food allergens that cats deal with in commercial pet food. Overall, this is a pretty low quality ingredient.
Based on the ingredients used in this formula, it is clearly a low quality formula. While most of the reviews are positive, most cat owners do not know what is good for their cat and what is not. Just because your cat seems to enjoy the meal, does not mean it is nutritionally ideal. The long term effects can be detrimental.
