Cat Nutrition Basics: What Vets Look For in Cat Food

Vets’ first consideration isn’t about whether you’re feeding your cat wet or dry food, it’s more about overall cat nutrition. “What matters most is that the diet—wet or dry—is complete, balanced, and appropriate for the cat’s life stage,” says Dr. Nita Vasudevan, veterinarian at Embrace Pet Insurance. To check that the food is complete and balanced, they’ll make sure it’s AAFCO-compliant. They’ll also check that the food is appropriate for the life stage of the cat, such as kitten, adult, or senior food. Finally, they’ll consider ingredient quality and protein sources.

Wet Food vs. Dry Food: What Vets Recommend (Quick Overview)

Overall, veterinarians agree that both wet food and dry food can be healthy. They often recommend wet food for certain health issues or when hydration is a concern. Dry food is suggested for its cost and convenience. 

When Vets Recommend Wet Food for Cats

Wet food tends to be higher in moisture and protein while being lower in carbs. For this reason, vets often lean towards wet food for cats with urinary tract or kidney issues, or who are working to manage their weight.

Hydration

Because wet food contains 70-80% water and kibble only 6-10%, wet food is a clear winner when it comes to hydration. As Dr. Nathaniel Rakestraw, DVM, veterinarian with TelaVets.com notes, cats evolved to get most of their water from food. Because of this, many cats eating dry food only don’t drink enough water to compensate, which can leave them dehydrated over time.  

Urinary and Kidney Issues

“There isn’t strong, universal evidence that wet food alone leads to longer lifespans compared to dry food, but there is good evidence that higher moisture intake supports urinary tract health,” says Dr. Vasudevan. Dr. Rakestraw adds that water helps dilute urine, which reduces the risk of crystal formation and lower urinary tract issues. He also points out that hydration is a key part of managing kidney disease in cats, and wet food is an easy way to increase water intake.

Blood Sugar and Diabetes Risk

Dry food requires binders or starches to help it keep its shape, which raises the carbohydrate content. Alternatively, wet food has a lower carb content, which minimizes blood sugar spikes. For cats with diabetes, vets often recommend low-carbohydrate wet food.

Weight Management

“Wet food can be helpful for weight management because it’s lower in calorie density and higher in water content, so cats feel fuller on fewer calories,” says Dr. Vasudevan. Dr. Rakestraw adds that it can be easier to overfeed your cat on dry food, especially if you free-feed. However, portion control is key for weight management, regardless of the diet type.

Palatability and Picky Eaters

The moisture content in wet food increases the aroma, which makes it more appealing to cats. It can also be gently warmed up, which some cats prefer. Wet cat food comes in many textures., including pâté, stews, shreds, or chunks in broth or gravy. This makes it easier to find food your cat loves. You can also use wet food to hide pills, which can be helpful if your cat is taking medication.

When Vets Recommend Dry Food for Cats

While dry food is lower in moisture, it is more cost-effective and can be more convenient. Dr. Rakestraw says that dry food is appropriate for healthy cats that maintain good hydration. Just make sure the food is nutritionally complete and you are serving appropriate portions.

Cost 

Vets often recommend dry food to cat owners on budgets or who have multiple cats. Cailin R. Heinze, VMD, MS, DACVIM (Nutrition), looked at the cost of feeding an average 10-pound cat. She found that dry food costs ranged from $0.23 to $0.97 per day, while wet food costs ranged from $1.22 to $5.77 per day. 

Convenience

While canned cat food is shelf-stable, it needs to be refrigerated after opening, with opened cans lasting 2-3 days in the refrigerator. On the other hand, an opened bag of kibble lasts for 4-6 weeks, provided the bag is kept sealed. This makes kibble more convenient for many cat owners. You can also use kibble in automatic and puzzle feeders, and you can leave it out for several hours, making it a better option for cats who prefer to graze.

Mixed Food Diet: Creating a Balance Diet for Cats

Wet cat food vs. dry cat food isn’t either/or. A mixed feeding approach can help create a more balanced diet for cats. ”Most of the time, veterinarians recommend feeding a mix of wet and dry as it gives you the best of both worlds—added hydration from wet food and the convenience of dry,” says Dr. Vasudevan. Exposing your cat to different types of food earlier on can also be helpful should you need to transition to a specialized diet when they are older.  When feeding your cat a mixed food diet, it’s important to prevent overfeeding. This means calculating the number of calories your cat needs per day and dividing them between wet and dry food.

This chart can guide you in choosing the best type of food for your cat.

How to Choose the Best Cat Food Brands

Vets recommend following these steps when choosing cat food:

1. Look for an AAFCO complete and balanced statement. This ensures that the food contains all the essential nutrients for your cat. 

2. Search for high-quality meat or seafood as the number one ingredient, such as chicken, rabbit, turkey, or salmon. 

3. Check that the food is appropriate for the life stage of your cat. Some manufacturers design foods specifically for kittens, pregnant or nursing cats, adults, or seniors, while others create options suitable for all life stages.

4. Avoid foods with too many fillers. This includes corn and corn syrup, beet pulp, artificial preservatives, and unnamed fats.

Wet Food vs. Dry Food: Frequently Asked Questions

 

Do vets recommend dry or wet food more?

Most vets recommend a mixed-food diet. This combines the hydration benefits of wet food with the lower cost and convenience of dry food.

Is wet cat food healthier than dry cat food?

No, neither wet cat food nor dry cat food is healthier. While wet cat food can help with hydration, both wet food and dry food can be complete, balanced diets. What’s best for your cat depends on their health needs and preferences. 

Can cats live on dry cat food alone?

Yes, cats can live on dry cat food alone provided it is high-quality and they stay hydrated. Having multiple water bowls, a water fountain, or flavoring your cat’s water with the juice from a tin of tuna or low-sodium chicken broth can encourage drinking. You can also soak your cat’s kibble in water. 

Does dry cat food clean cats’ teeth?

The abrasive nature of dry cat food can help to remove tartar from cats’ teeth. However, many cats swallow their kibble whole, meaning they miss out on this benefit. 

What’s the best cat food for urinary health?

Wet cat food is often recommended for urinary health as the extra hydration helps to reduce the risk of urinary tract infections and stones. For cats with urinary tract or kidney issues, your vet may recommend a prescription diet. 

How do I switch my cat from dry to wet food?

It’s best to transition from dry to wet food gradually over 10 days. Start with a mix of 75% old food and 25% new food for 3 days. Then, move to a 50/50 mix for another 3 days and then 75% new food and 25% old food for 3 days. On day 10, you can fully transition to new food. If at any point your cat refuses their food, revert back to the previous mix for a few more days.

The Final Verdict: Wet Food vs. Dry Food for Cats

When it comes to wet food vs. dry food for cats: what vets recommend, most veterinarians agree that a mixed feeding approach is often ideal. This can create a more balanced diet for cats, supporting hydration while being convenient and cost-effective. However, both wet and dry foods can support overall cat nutrition and health. 

With all this in mind, we know that cats can be picky, so choosing the best cat food brands comes down to finding a nutritionally complete food that your cat enjoys. Many cat owners find success introducing high-quality wet food, such as Tuft & Paw Really Great Cat Food, that is rich in protein and free from fillers while containing all the nutrients cats need.
