Hill’S Science Diet Cat Food Review (12 Products)

Hill's Pet Nutrition is now a global pet food company known for selling scientifically created foods that are designed to help our pets live their best lives.

But that is not how Hill's began. When Burton Hill created the company in 1907, it was originally known as Hill Rendering Works.

At this moment, they were not a pet food firm. Rather, they were a rendering service in Topeka, Kansas, with a contract to dispose of dead and lame animals.

Hill's has gone a long way since its humble beginnings as a rendering plant.

Today, they have a massive team of over 220 veterinarians, nutritionists, technicians, and food scientists developing their pet foods, and they conduct their research in the world-class Hill research facility, which is still located in Topeka, Kansas, where the Hill's company was founded more than 100 years ago.

Hill's is committed to developing products that improve the health of our pets, thus every ingredient is subjected to rigorous testing to ensure that anything that makes its way into a Hill's pet food is of excellent quality.

They provide premium cat feeds for cats of all ages, as well as customized diets for cats who require special attention.

Let's see what type of variety and nutritional value are produced for cats in this Hill’s Science Diet cat food review below from BestForPets (bestforpets.org).

Hill's Science Diet Cat Food Evaluation

Who makes Hill’s Cat Food?

Hill’s has evolved dramatically since its humble beginnings as a rendering service in Kansas. They’ve grown into a global firm, with items sold in 86 countries around the world.

Hill’s is now owned by Colgate-Palmolive, which purchased the company in 1976.

Despite being controlled by such a large multinational, Hill’s still manufactures all of its food in its own factories in the United States.

Which Cats Are Hill’s Best Suited For?

If you check through Hill’s extensive catalog of cat food items, you’ll see that they create a diverse range of products ideal for various cats.

For example, they produce high-quality dry and wet cat food for adult cats. They also make food for kittens and seniors, as well as those with sensitive stomachs and cats with skin problems.

Hill’s provides an extensive line of prescription pet meals for cats with major health issues that require veterinary authorization to purchase.

Cat owners who choose to feed their kitty a particular diet will find grain-free recipes and other options.

Which cats and owners would benefit from a different brand?

Hill’s creates food to accommodate any feline, but they aren’t the best fit for everyone. In truth, it’s impossible to account for a cat’s tastes.

Even if you sample various variations, some finicky eaters may not be interested in Hill’s.

However, we’ve had success in getting fussy eaters to eat Hill’s when they wouldn’t eat other foods, so it may go either way.

Another factor that may put you off Hill’s cat food is the price. These are branded as premium pet feeds and come with a premium price tag.

Feeding Hill’s to your cat will cost significantly more than feeding other brands.

Hill’s Science Diet’s Key Ingredients

The ingredient list is the best way to choose whether you want to feed Hill’s to your cat.

The elements at the top of the list are the most common, while those towards the bottom are present in the smallest amounts.

The first five ingredients in Hill’s Science Diet Adult Dry Cat Food, one of the company’s most popular products, are:

  • Chicken
  • Wheat Whole Grain
  • Gluten-Free Corn Meal
  • Fat from Pork
  • Chicken Dinner

Protein from Animals

Three of the five major ingredients in this combination are derived from animals, which is ideal for cats because they are obligate carnivores. Cats obtain all of their nutrition from animals and do not require carbs.

Grain Whole

There are also two substances that aren’t sourced from animals. Cats may not require carbohydrates, yet all dry cat meals do.

They supply calories for your cat, yet most of them are wasted because your cat can’t digest carbohydrates properly. However, they also function as a filler and glue the food together.

If your cat must have carbohydrates, whole grains are the best choice. Whole grain wheat, as you can see, is clearly a whole grain, making it one of the better selections for a dry cat food filler.

Filler Protein on the Cheap

Corn gluten meal, on the other hand, is not a favorite of ours. It’s a low-cost filler protein that improves the food’s overall protein level.

Corn protein, on the other hand, is difficult for cats to digest because it is a carbohydrate, thus it isn’t as useful as animal protein.

History of Recalls

Hill’s has only had a few recalls over the years, the most recent being in 2019.

A recall was issued in early 2019 when dangerously high levels of vitamin D were discovered in several batches of Hill’s food.

This resulted in two outcomes. First, Hill’s tightened its quality assurance procedures. Following that, a class-action lawsuit was filed against Hill’s because of the high quantities of vitamin D.

Although it is not a true recall, Hill’s voluntarily recalled certain of its dog food products in 2015 due to labeling concerns.

Due to salmonella contamination, 62 bags of Hill’s pet food were recalled in Nevada, California, and Hawaii in 2014.

Hill’s, like most pet food brands at the time, was recalled in April 2007 due to melamine contamination.


Dry Cat Food Hill’s Science Diet Sensitive Stomach & Skin

The Hill’s Sensitive Stomach & Skin formula is somewhat pricey for dry cat food. However, it also provides some advantages not found in conventional cat meals.

It’s high in vitamin E and omega fatty acids, for example, which can help keep your cat’s skin and coat healthy and feeling terrific.

However, this meal does more than just keep your cat looking good. It also contains prebiotic fiber, which is beneficial to intestinal health.

This mixture, designed specifically for cats with sensitive stomachs, is easy to digest and will not upset your cat’s stomach.

This food’s first ingredient is chicken, guaranteeing that your cat is getting great protein sources.

And with a minimum of 29% crude protein, you can be confident that they are getting enough protein overall.

This food contains almost every significant ingredient that is an animal product, making it ideal for cats.

There are chicken, turkey giblets, pork byproducts, hog liver, and other items available. And these elements are also quite appealing to finicky eaters.

Despite being manufactured with a variety of animal-based protein sources, this meal contains less protein than other wet cat foods we’ve tried.

At 5.5 ounces each can, the servings are also quite generous. Small and medium-sized cats may not require as much. Still, the quality is superb, which is our primary concern.


  • Made with premium whole-food protein sources
  • A diverse protein profile is provided by a variety of protein sources.
  • A fantastic option for finicky eaters.


  • Protein level is lower than in other wet cat diets.
  • The portions are a little large.


Hill’s Science Diet Multiple Advantages Food for Dry Cats

With so many distinct health-boosting blends to choose from, it might be difficult to settle on a single Hill’s recipe.

However, with multiple benefit cat food, you can receive all of the benefits you want in a one combination. Hairballs are a frequent concern among cat owners.

This combination contains natural fibers that can help minimize the number of hairballs your cat coughs up.

It’s also designed to assist your cat maintain a healthy weight and avoid obesity.

According to the nutritional panel, this item includes at least 30% crude protein, with chicken listed as the first component.

That’s excellent, but some of the other ingredients, such as maize gluten meal and wheat gluten, didn’t sit well with us.

However, we liked the antioxidants and vitamins offered for immune system support.


  • Natural fibers are used to reduce hairballs.
  • Aids in the maintenance of a healthy weight
  • Antioxidants and vitamins are included to help the immune system.
  • Minimum crude protein content of 30%


  • Some of the ingredients aren’t among our favorites.

This dish has 31% protein in total, but it is vital to note that the next three ingredients are low-quality grains and fillers.

Whole grain wheat is a healthy food for humans, but it has minimal nutritional value for cats and is difficult to digest.

The same is true for maize gluten meal, which is frequently utilized as a source of plant-based protein in low-quality cat meals.
