Hairballs form when cats groom themselves or each other, two natural and healthy behaviors. Small amounts of hair can pass through your cat’s system and leave their body as waste. But if cats consume too much hair, this excess could end up on your carpet as a hairball — or worse, become stuck inside your cat’s digestive tract and cause an obstruction.

A change in diet shouldn’t replace brushing your cat, but high-fiber cat food can help hair move through the digestive system, says Larsen. “The goal is to use fiber to pull the hair along the gastrointestinal tract so it’s defecated rather than balling up in the stomach,” she says. Some key ingredients that help promote this movement include rice hull, pea fiber, and cellulose. 

Plus, there’s another benefit to fiber-rich diets for cats, Larsen says. High-fiber recipes can keep cats feeling fuller for longer while reducing their calorie intake. So, you might consider a diet with more fiber if your vet recommends weight loss for your cat.

When shopping for the best dry cat food for your kitten, adult, or senior cat, you’ll want to consider the following criteria:

AAFCO nutritional adequacy statement: The most basic measure of nutritionally complete cat food is an AAFCO statement on the label. AAFCO is a nonprofit organization that defines the standard nutritional requirements for pet food and animal feed. Food with an AAFCO statement for growth or all life stages is guaranteed to be complete and balanced for kittens, while food with an AAFCO statement for maintenance or all life stages is guaranteed to be complete and balanced for adult cats.

Guaranteed analysis and nutrient profiles: The guaranteed analysis consists of the percentages of protein, fat, and other important nutrients in a food. Food for kittens should have a minimum of 30% protein and 9% fat, and food for adult cats should have a minimum of 26% protein and 9% fat. Food for cats of any age should also contain other essential nutrients, including amino acids like taurine, fatty acids, minerals, and vitamins.

Key ingredients: The ingredients on a pet food label appear in order of weight. Because cats are obligate carnivores, proteins in the form of whole meat or meat meal should come first on the ingredients list.

Expert formulations: For this guide, we prioritized brands with a dedicated nutrition expert on staff, which aligns with the World Small Animal Veterinary Association (WSAVA) guidelines and our experts’ guidance. We also opted for brands active in research on small animal nutrition, as well as brands that collaborate with universities and colleges.  

Manufacturing standards: When selecting a cat food brand, consider a manufacturer’s quality control measures and the types of facilities they use. For instance, manufacturers that own their plants have more control over the ingredients in the recipe and the food your cat consumes. Just keep in mind that it’s not enough for a brand to say they conduct quality control. Pet food companies should also provide information about their quality control practices on their website or upon request. 

Calorie content: The calorie content of cat food is listed in kilocalories (kcals). Your cat will have different calorie needs, depending on their age and activity level. Kittens grow quickly in their first year, and all that growth requires plenty of energy. Therefore, kittens should eat multiple meals per day without calorie restrictions. As your kitten approaches 9 to 12 months of age, talk to your vet about their ideal body condition, weight, and caloric needs.

Once cats reach their adult years, the amount of food they should eat depends on their weight, energy level, breed, and overall health. Your vet can offer more detailed and personalized guidance about how many calories your cat requires per day.

To select the best dry cat foods for this guide, we consulted three veterinary nutritionists.

Dr. Deb Zoran is a board-certified small animal internist, nutritionist, and professor of small animal clinical sciences at the School of Veterinary Medicine and Biomedical Sciences, Texas A&M University. Zoran’s expertise helped us better understand cat nutrition and quality food. She also shared her personal feeding preferences, which may not represent specific endorsements shared by Texas A&M University.

Dr. Jennifer Larsen is a board-certified veterinarian, distinguished member of the American College of Veterinary Nutrition, and a professor of clinical nutrition at the School of Veterinary Medicine, University of California, Davis. Larsen’s expertise helped us better understand senior cat nutrition and the role of high-fiber diets in feline nutrition and well-being.

Dr. Korinn Saker is a board-certified veterinarian, distinguished member of the American College of Veterinary Nutrition, and a professor of clinical nutrition at the College of Veterinary Medicine, North Carolina State University. Saker’s expertise helped improve our understanding of feline food intolerance and sensitivities, as well as an indoor cat’s metabolic needs.

We also consulted guidelines and recommendations from other organizations, including AAFCO and the WSAVA Global Nutrition Guidelines.

What are the benefits of dry cat food?

Dry food is a popular choice for its affordability, convenience, and ease of storage. “There is a small amount of evidence that some, very few and specific dry cat foods may have some oral health and dental benefits,” says Dr. Bruce Kornreich, a board-certified veterinary cardiologist and director of the Cornell Feline Health Center at Cornell University College of Veterinary Medicine. “But the most important thing that cat owners can do to maintain their cat’s oral health is to brush their cat’s teeth,” he says.

Which dry cat food brand is the healthiest?

To ensure you’re purchasing quality food for your cat, Zoran recommends first checking the label for the AAFCO statement. That way, you’ll know the recipe meets your cat’s nutritional needs. Then, you might consider other brand attributes, including whether their food has ever been recalled, if they employ board-certified nutritionists, and whether they participate in research studies. If a company is reputable, you can generally trust what they print on the label, according to Zoran. 

What is the best dry food to give a cat?

There’s not a perfect dry food choice that fits every cat or kitten. Instead, ask your veterinarian for food recommendations tailored to your pet. They may be able to suggest some options that meet your cat’s specific nutritional and calorie needs, based on their age, body condition, and overall health.  

Is it OK to feed cats dry food only?

Zoran recommends feeding cats a combination of dry and wet food from different brands starting at a young age. This encourages food flexibility in cats and can prevent them from becoming picky eaters — which may prove particularly helpful when their preferred food is unavailable, recipes change, or they require a prescription diet.

Do vets recommend dry or wet food for cats?

Both canned and dry food choices can meet the nutritional needs of cats and kittens, as long as they’re labeled with the AAFCO statement for your cat’s specific life stage. The ideal food for your cat generally depends on your budget, along with their overall health and food preferences. However, to prevent finicky tastes and food inflexibility, Zoran recommends rotating textures, proteins, and brands from a young age.

Should I leave dry food out for my cat all day?

Zoran doesn’t recommend free-feeding cats. “It is exceptionally hard to regulate a cat’s weight and proper amount of food by free-choice feeding,” she says. Instead, portion their food into two to three small meals a day. If you’re not sure how much to feed your cat, you can ask your vet for more specific guidance based on your cat’s age, ideal weight, and overall health.
