Hill’s Science Diet remains one of the top pet food companies on the market. They have a huge following and produce hundreds of different formulas, many of which treat chronic diseases. However, they also produce a variety of “normal” foods, including some for kittens.

1. Best Overall: Hill’s Science Diet Indoor Kitten Dry Cat Food

For most kittens, we recommend this dry formula by Hill’s Science Diet. It includes chicken as the first ingredient, as well as chicken fat further down the ingredient list. With that said, this formula also relies on wheat gluten, which is a protein concentrate from wheat.

Of course, this ingredient holds some controversy. However, it does provide extra protein for your feline. This formula also includes brown rice, which is a whole grain that provides fiber and some nutrients.

For brain and eye development, this formula includes DHA from fish oil. This ingredient provides some extra support for your cat’s development. Plus, this formula contains antioxidants, as well. These improve your cat’s immune system by preventing oxidative stress.

Plus, we love that this formula does not contain artificial colors, preservatives, or flavors. Therefore, it remains a high-quality option for most kittens.

2. Best Wet Cat Food: Hill’s Science Diet Roasted Chicken & Rice Medley Canned Cat Food

Many cats do best on wet cat food, as it provides extra moisture. This moisture helps prevent UTIs and other urinary tract problems. Plus, extra hydration is rarely a bad thing.

Compared to most formulas on this list, this wet food includes more meat-based ingredients. Chicken broth appears as the first ingredient, which helps add moisture and nutrients to this wet cat food. Whole chicken appears as the second ingredient, while pork liver is the third.

Based on all these ingredients, this formula includes lots of amino acids to improve your cat’s growth and development. However, wheat gluten appears as the fifth ingredient. Keep this in mind when looking at the protein content of this food.

We love that this formula doesn’t contain any artificial flavors or preservatives.

3. Best for Digestive Health: Hill’s Prescription Diet I/D Digestive Care with Chicken

Sometimes, kittens and other cats need a bit of extra digestive support. Whether they have an underlying condition or just a sensitive tummy, we highly recommend this formula for your feline. However, it does require a veterinary prescription, which is something you need to keep in mind before trying to purchase it.

Overall, this food is for cats that really need digestive support.

This formula includes highly digestible protein and fat, which helps your feline assimilate nutrients and avoid digestive problems. Plus, Hill’s has included many sources of fiber. For most digestive problems, fiber remains vital for digestive care and support.

This formula lists chicken as the first ingredient. This ingredient helps improve digestion, as chicken is extremely digestible.

4. Best Pouch Recipe: Hill’s Science Diet Kitten Tender Chicken Recipe

This formula features an extremely tender texture that’s sure to entice kittens. Plus, most kittens have no trouble eating it. Therefore, for very tiny kittens, you may want to consider this delectable food.

To increase the water content, this food contains water as the first ingredient. Plus, chicken and pork liver are the second and third ingredients. Therefore, Hill’s included a lot of meat in this formula, as well.

On top of meat protein, soy protein isolate and wheat gluten have also been included. These two ingredients seriously increase the protein content of these foods. However, they are not meat-based and therefore may not contain all the amino acids that your cat needs.

Many customers reported that they loved the pouch this food comes in. Each single-serve pouch allows you to quickly and easily feed your kitten.

5. Best Turkey-Based Kitten Food: Hill’s Science Diet Kitten Savory Turkey Entree

While most Hill’s Science Diet features chicken as the main ingredient, this recipe lists turkey as the primary flavor. The company added water first to increase the moisture content. Many cats need the extra moisture, and this wet food provides just that.

However, turkey does appear as the second ingredient. Therefore, this formula works well for cats that can’t have or don’t like chicken. With that said, this formula does include some chicken. For instance, chicken liver flavor appears further down on the list.

Therefore, it is not best for kittens that are extremely sensitive to chicken. However, for only moderate allergies, this formula may work just fine.

Soy protein isolate and corn gluten meal both appear pretty high on the ingredient list. For this reason, we highly recommend keeping this in mind when looking at the overall protein content. Not all of the protein comes from meat.

6. Best Fish-Based Kitten Food: Hill’s Science Diet Kitten Savory Salmon Entree

Fish provide many benefits to cats that you might enjoy. Firstly, salmon is high in omega fatty acids, which support skin and coat health. However, despite its name, salmon doesn’t appear until the third ingredient in this food. Therefore, while it does contain salmon, it contains more other ingredients.

Water appears as the first ingredient. This improves the moisture content of this cat food, which helps with many different health problems. Plus, picky cats also enjoy increased moisture content in many cases.

However, pork liver appears as the second ingredient. While this ingredient is high-quality, it is far from salmon. Don’t let the advertising fool you. Plus, pork by-products and chicken fat appear high on the ingredient list, as well.

This formula includes high levels of fiber, supporting your kitten’s digestive tract. Fiber remains vital for many cats, as it helps regulate your cat’s digestive system. This recipe also includes vitamins C and E, which may help improve your cat’s immune health.

Choosing the Best: What to Look For

When you’re choosing the best Hill’s Science Diet kitten food, there are several things you should keep in mind. Not all of these foods are the same. Therefore, you’ll need to carefully consider each recipe’s ingredients, nutritional value, grain inclusion, and price before making your purchase.

Ingredients

Generally, you want to see meat as the primary ingredient in any cat food. Cats are obligate carnivores, which means that they thrive on a diet containing mostly meat. They need to eat meat to survive.

Therefore, it only makes sense to choose a cat food that’s high in meat for your kitten.

Plus, you also want to consider not purchasing foods that include any controversial ingredients. These foods may not necessarily harm your feline, but they are rarely the best option.

Nutritional Value

All kitten foods on the market meet AAFCO guidelines for kitten formulas. In other words, they all count as complete diets. However, these formulas often include other nutrients like added omega fatty acids and vitamin C.

These added nutrients can provide support for many felines. If your cat has a specific health problem, these ingredients may be even more important.

Grain Inclusion

Grains remain a controversial subject despite being in most cat foods. For the most part, there currently is no evidence that states whether or not these ingredients should be in cat food. They do provide fiber and some nutrients when used in their whole form.

Therefore, we recommend that most cats consume either no grains or whole grains. Generally, whole grains are the best option.

Many people choose grain-free foods because they often appear to be low in carbohydrates. However, many grain-free cat foods contain lots of starchy veggies. Therefore, a grain-free cat food often contains starchy veggies.

Price

Hill’s Science Diet remains a more expensive cat food brand. However, this higher expense pays for the food research. This brand employs many veterinary nutritionists, which is surprisingly hard to find.

Therefore, you’re getting something for the increased price.

Verified Reviews: Users’ Experiences

Most user complaints were about each recipe’s ingredient list. For instance, many users were disappointed with the salmon wet food, as the first few ingredients were not salmon. Many users felt tricked by the advertising. (This is one reason we recommend always reading the ingredient list before making a purchase.)

With that said, most reviews were extremely positive. Users regularly gave the kitten indoor dry food rave reviews. According to most reviews, cats love it, and it appears to keep them healthy.

However, there were some complaints about each dry food option involving the flavor. Evidently, some cats simply don’t like how this brand tastes. Still, we expect some of this is due to the lack of artificial flavors. If your kitten is used to artificial flavors, switching to any food without them may be a bit troublesome.
