Skip To

Cats are curious, complex, and captivating creatures. And just as no two cats are exactly alike, the nutritional needs of our feline friends can be equally varied. Some need extra energy to fuel their active lifestyle. Others require fewer calories to maintain a healthy weight. Some have lots of food sensitivities. And some have lots of, well…hairballs. 

Staying on top of your cat’s health, wellness, and nutritional needs can be challenging for any pet parent. Luckily, Hill’s Science Diet has a wide variety of cat food formulas designed to meet the ever-changing needs of cats, through every age and stage of their life. 

But what does that really mean? To make deciding what goes in your cat’s dinner bowl easier to understand, here’s a helpful overview of Hill’s Science Diet dry cat food formulas, how they work, and what that means for your cat.

Why Choose Hill’s Science Diet Dry Cat Food?

Hill’s Pet Nutrition has a legacy in the pet food industry that stretches all the way back to 1907, when the company was founded. Hill’s Science Diet is the brand’s premium line of pet food, featuring formulas developed in partnership with over 200 veterinarians, nutritionists, and food scientists.

When it comes to choosing a cat food that’s tailored to address your cat’s specific nutritional needs or health considerations, Hill’s Science Diet cat food formulas provide plenty of options. What’s more, every formula is perfectly balanced to contain precisely what domestic cats need to survive.

Cats are obligate carnivores, meaning they — like their ancestors in the wild — require a diet rich in animal proteins for survival. Hill’s Science Diet dry cat food makes feeding your cat a balanced, protein-rich diet convenient, affordable, and nutritionally sound. 

Not only does Hill’s Science Diet kibble for cats contain high-quality proteins cats need to build lean, healthy muscles, it also contains all the fats, fiber, vitamins, and minerals modern cats have evolved to thrive upon. That includes essential nutrients like taurine, which cats used to derive from prey animals, and limited amounts of easily digestible carbohydrates.

All of this combined is what makes Hill’s Pet Nutrition the #1 veterinarian-recommended pet food over any other brand. Dr. Dawn Filos, DVM, counts herself among these veterinarians who recommend Hill’s Science Diet cat food. “I do, often, and have done so for my entire 30+ year career,” she says.   

“I have personally used Hill’s Science Diet for most of my pets, “ she adds. “They provide high-quality, reasonably priced diets, readily available in pet stores.” Filos says she also appreciates that Hill’s is one of the very few pet food companies that do extensive research on their diets, which are nutritionally well balanced and adhere to stringent health and safety guidelines.

Additional Considerations

As we mentioned before, cats can be complex. So if you have a kitty who has more than one health consideration, never fear. Hill’s Science Diet formulas often address multiple categories at once. For example, if urinary health is a priority for your cat and you’d prefer fewer hairballs in your life, Hill’s Science Diet Urinary Hairball Control Adult dry cat food could be just the formula you’re looking for.

Which Hill’s Science Diet Formula is Right for Your Cat? 

Given the extensive options Hill’s Science Diet offers, feeding your cat a diet that’s fine-tuned to their specific nutritional needs is easier and more affordable than ever before. 

Now that you’ve learned how Hill’s Science Diet dry cat food formulas work and the benefits they provide, you can hand-pick the option that will help your cat thrive. And if you’re still unsure, you can take this easy quiz to zero in on the formula that fits your pet best.

However, while pet parents often feel they know their cats best, consulting your veterinarian is an important part of selecting the right Hill’s Science Diet formula to fit your cat’s current health profile and objectives. 

The right diet plays a critical role in promoting and maintaining good health. But food alone is not a sufficient treatment for diagnosed health problems, such as diseases or chronic illnesses.  

“If the pet has specific health issues, only utilize recommendations from your veterinarian for meeting the pet’s dietary needs,” recommends Dr. Michael Fleck, DVM, founder and medical director of the Animal Medical Center of Bradenton and co-host of The Pet Buzz, a popular, pet-centered radio show. 

Choosing the wrong diet, he warns, could worsen health conditions that could have long-term consequences. And since the mission of Hill’s Science Diet pet food is “to help enrich and lengthen the special relationships between people and their pets,” that’s definitely something you want to avoid.

So talk to your veterinarian if you have any questions about which Hill’s Science Diet dry cat food formula is best. They’re likely to have some good suggestions for you and your cat.
