Cat Food Debate: Wet vs Dry Explained
As a cat owner, you’ve probably stood in the pet food aisle staring at the bewildering array of options. The great cat food debate: wet, dry, or a mix of both? This is a hot topic, and for good reason—your cat’s diet forms the foundation of their health.
At all4petstore, we know how important it is to get it right. So, let’s break down the key differences to help you decide what’s best for your furry companion. The cat food debate is a big one, but understanding the basics makes it much easier to navigate.

The Case for Wet Cat Food
Brands sell wet food in pouches or cans, and it typically has a moisture content of around 70-80%. This high water content is its biggest advantage.
Pros of Wet Food:
- Hydration: Cats are descended from desert-dwelling ancestors and have a naturally low thirst drive. For this reason, they often don’t drink enough water on their own. Wet food is a fantastic way to boost their daily water intake, which is crucial for preventing kidney and urinary tract issues. Vets often recommend a wet food diet for cats with pre-existing conditions like kidney disease or a history of bladder stones.
- Palatability: The stronger aroma and softer texture of wet food make it highly appealing to even the pickiest of eaters. Furthermore, it’s easier to chew, which makes it an excellent option for kittens, older cats, or felines with dental issues. Brands like Lily’s Kitchen and Applaws offer a high-quality, high-moisture content that is both delicious and beneficial for hydration. The tasty, shredded textures found in brands like Felix As Good As It Looks or the rich pâtés from Sheba can tempt even the fussiest felines.
- Weight Management: Wet food is generally less calorie-dense than dry kibble. The high moisture content helps cats feel full, which can be a useful tool for managing weight and preventing obesity.
- Protein-Rich: Wet food typically has a higher protein content and lower carbohydrates, which more closely aligns with a cat’s natural diet as an obligate carnivore.
Cons of Wet Food:
- Cost: Wet food is usually more expensive than dry food on a per-serving basis.
- Shelf Life: Once you open it, wet food spoils quickly and you must refrigerate it. You can’t leave it out for long periods, which may not be ideal for cats who like to graze throughout the day.
- Mess: You might find wet food messier to serve, and it can be a bit more difficult to clean up.

The Case for Dry Cat Food (Kibble)
Dry food is a popular and convenient choice for many households. It’s a hard, crunchy kibble with a moisture content of around 10%.
Convenience and Cost Benefits
Pros of Dry Food:
- Convenience and Affordability: Dry food is cost-effective, easy to store, and has a very long shelf life. You can buy it in large bags without worrying about it going bad. Popular and reliable options include Purina ONE and Iams, which offer great value for money.
- “Free-Feeding” Friendly: Since it doesn’t spoil quickly, you can leave dry food out in a bowl all day for cats who prefer to eat small, frequent meals. This also makes it perfect for use in automatic feeders and puzzle toys, which provide mental stimulation.
Health and Diet Considerations
- Dental Health (with a caveat): The crunchy texture of dry kibble can help scrape away plaque and tartar buildup on the surface of a cat’s teeth. However, it’s important to note that this is not a substitute for regular dental care, and some experts argue that its effectiveness is limited unless it’s a specially formulated dental-health kibble. Brands like Hill’s Science Plan Oral Care are specifically designed to help support healthy teeth.
Cons of Dry Food:
- Low Moisture Content: This is the main drawback. Cats on an exclusively dry food diet must be diligent drinkers to stay properly hydrated. If they aren’t, they can be at a higher risk for urinary and kidney problems.
- Higher Carbohydrates: To create the kibble’s shape, starches are required. Consequently, dry food often contains higher levels of carbohydrates, which can contribute to weight gain if you don’t portion-control it.
- Can be difficult to chew: Cats with missing teeth or painful dental issues may find dry food uncomfortable to eat.
The Best of Both Worlds: A Mixed Diet
For many cat owners, the solution isn’t choosing one over the other but combining them. A “mixed feeding” approach offers the benefits of both. You could, for example, serve a meal of wet food in the morning and evening for hydration and a protein boost, while leaving a small, measured amount of dry food out during the day for snacking and convenience.
The Final Verdict
Ultimately, the best choice depends on your individual cat’s health, age, lifestyle, and preferences. We always recommend consulting with your vet to determine the ideal diet for your feline friend. A complete and balanced diet is key, whether it’s wet, dry, or a combination of the two.
