There are numerous such formulas in the market, and the Science Diet Mature Adult Indoor dry formula is one of them. This formula is claimed to contain all the nutrients your cat needs to lead a healthy indoor lifestyle.

An overview of the first five 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.
Powdered cellulose is a cheap filler ingredient. It is obtain as a pulp from fibrous plant material and highly refined. Once processed, it looks and feels very similar to sawdust. Cellulose is used in a wide number of ways. In addition to being added to pet food, it is used quite a bit in human foods, but can also be used for things like insulation, rope making, and textiles. Just like in humans, this ingredient is indigestible for cats. There is no hard evidence to suggest this ingredient is unhealthy, but it wouldn’t be considered a higher quality ingredient, either.
Other ingredients in the formula
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.
A good source of carbohydrates, vitamins, and minerals, carrots are becoming more common in pet foods. This ingredient is also known to boost the immune system and help promote healthy eyes in cats as well as providing a good source of fiber.
Peas are becoming more and more common in pet foods today, especially those listed as grain-free, holistic, or natural pet foods. While peas are certainly not grains, they serve much the same purpose. It mostly acts as a filler and a cheap way to increase the protein percentage of the food. However, cats receive almost no nutritional value from peas. Since cats are obligate carnivores, they require proteins from meat based ingredients. There is very little research that has been performed on the long term effects of cats consuming peas. We do know that peas can cause runny poop or digestion issues in dogs, but the full effect on cats remains a bit of an unknown. At best, this ingredient will act as a filler and will not provide much nutritional value, if any, to your cat.
Oat fiber is produced from food-grade oat hulls and is mostly added for texture and binding purposes. It is sometimes used to help give food a lighter and browner color as well. Cats and dogs have no absolute physiologic need for this ingredient, although animals eating processed commercial foods appear to benefit from the addition of fiber.
Is this an allergy causing formula?
The Science Diet Mature Adult Indoor cat formula does contain some allergy causing ingredients. This makes it unsuitable for cats with allergies to food ingredients.
A nutritive source of carbohydrates that should have been used in the place of grain wheat
Potatoes – Potatoes provide a lot of carbs and unfortunately, cats do not digest carbs well and it can also lead to weight gain. This ingredient is becoming more popular in “grain-free” cat foods because while potatoes are not grains, they serve much the same purpose by acting as a non-nutritious filler. The good news is potatoes are complex carbs. These complex carbs are easier to digest than whole grains and also don’t spike blood sugar levels like the simple carbs do. But, anyway you cut it… carbs are carbs and cats don’t need them. This is a rather non-nutritious ingredient.
This is yet another weak formula under the science diet brand. Just like all other science diet formulas, this too contains several allergy causing ingredients. It is also short on protein with the main protein source being insufficient.
