Dry Cat Food. A Recipe for Feline Health Disasters?


There is an ongoing debate around whether dry cat food is healthy for cats or may cause health issues. With the majority of cat owners feeding dry food, often following the recommendation of their veterinarian, it’s an important topic to understand. This article will dive into the potential benefits and risks of feeding dry cat food. We’ll explore ingredients commonly found in dry foods, look at alternatives like wet food or raw diets, and provide key takeaways to help you make the best decision for your feline friend.

Dry vs Wet Cat Food

There are some key differences between dry and wet cat food when it comes to nutritional composition, texture, and mouthfeel.

Dry cat food typically contains more carbohydrates and plant-based proteins than wet food. It has a lower moisture content, usually around 10%, whereas canned wet food contains around 75% moisture. With less water, dry food is more calorically dense. Nutrients. The protein and fat content can vary in dry vs. wet foods depending on the specific formulas.

In terms of texture, dry cat food contains kibble or crunchy pieces. It is intended to help keep cats’ teeth clean. However, some experts argue the hard texture does not provide enough abrasion. Wet food has a smooth, pâté-like texture that some cats prefer. It also has more aroma and flavor from higher moisture content. The softer texture may be easier for some cats to chew and digest.

Benefits of Dry Food

There are some advantages to feeding cats dry food. First, dry food is very convenient and easy to serve. The kibble can be left out in a bowl for cats to snack on throughout the day without spoiling. This allows cat owners to easily make food available at all times without preparing fresh meals multiple times per day.

Another commonly cited benefit of dry cat food is potential dental health advantages. The crunchy texture may help scrape away tartar and plaque as cats chew. However, wet food likely provides other oral health benefits by increasing hydration through the mouth and reducing the need for plaque-causing carbohydrate fillers in dry food [1].

Finally, dry food is significantly less expensive than wet cat food. The lower moisture content allows it to be packaged, shipped, and stored very efficiently. This makes dry food the budget friendly choice for many cat owners.

Downsides of Dry Food

While dry food provides some benefits in terms of convenience and dental health, there are some significant downsides to feeding cats only dry food that pet owners should be aware of:

Dehydration risk – Cats have a low thirst drive and do not drink enough water on their own to make up for the lack of moisture in dry food. This can lead to chronic mild dehydration, which stresses the kidneys over time and can predispose cats to kidney disease and urinary tract infections (Pros and Cons of Dry Cat Foods).

Urinary tract problems – The concentrated urine from not getting enough water can also lead to feline lower urinary tract disease (FLUTD). This refers to conditions like bladder stones, blockages, and infections (Is Dry Food Bad For Cats?).

Diabetes – Dry food is very high in carbohydrates, which can increase a cat’s risk for obesity and diabetes when fed free-choice. The carbs cause blood sugar spikes and place extra strain on the pancreas to produce insulin (10 Reasons Why Dry Food Is Bad for Cats).

Obesity – Because dry food is calorie-dense yet low in moisture, it is very easy for cats to overeat. This leads to obesity, which strains the joints and heart and predisposes cats to diabetes, among other problems.

Ingredients in Dry Cat Food

Dry cat food typically contains a variety of ingredients, some more nutritious for cats than others. Some key ingredients to pay attention to include:

Carbohydrate sources: Many dry foods use high amounts of carbohydrates like corn, wheat, and soy as fillers. Cats don’t need high amounts of carbs, and these inexpensive plant-based ingredients can sometimes cause allergic reactions or digestive issues (Source).

Meat meals vs whole meats: Whole meats like chicken, turkey, or fish are more nutritious than generic “meat meals.” Meat meals are rendered meat sources that lose nutrients in processing. Look for whole meats as the first ingredients (Source).

Preservatives: Dry food requires more preservatives to prevent spoilage. While essential, some cats may react to common preservatives like BHA, BHT, and ethoxyquin. Limiting dry food can reduce preservative exposure (Source).

Wet Food as an Alternative

Wet cat food has a number of advantages over dry food that may make it a healthier choice. The most significant benefit of wet food is the higher moisture content. Cats have a low thirst drive and often do not drink enough water, making hydration a challenge on an all-dry diet. Wet foods contain about 75-85% moisture versus only 5-10% in dry food. This increased fluid intake from wet food can help with urinary tract health.

Wet foods also tend to have fewer carbohydrates than dry kibble. Cats are obligate carnivores and do not have an inherent need for carbs in their diet. Some vets recommend reducing carbs to help manage conditions like diabetes and obesity. Additionally, wet foods often contain more meat-based ingredients. The high protein content supports strong muscles and lean body composition.

Overall, incorporating wet foods into a cat’s diet can provide nutritional advantages. Many experts recommend feeding a combination of wet and dry or transitioning to fully wet food if possible. Check with your veterinarian to determine the best diet plan for your individual cat.


Transitioning from Dry to Wet

When transitioning a cat from dry food to wet food, it’s important to gradually mix the two foods together over time. According to CatsMeowVets, you should start by leaving dry food down for 20 minutes at your cat’s normal feeding time. Remove any uneaten dry food after 20 minutes, then repeat this process again in 8-12 hours depending on if you feed 2 or 3 times per day. Slowly decrease the amount of time the dry food is left down over a 7-14 day period.

Providing consistent feeding times is also key when transitioning foods. Keep meals at the same time each day and slowly adjust the ratio of dry to wet food. Cats do best on a routine. According to Wellness Pet Food, start by adding a small portion of the new wet food and keep increasing the ratio gradually over 2-3 weeks.

You may need to try different textures of wet food as well during the transition. Some cats prefer pates, others gravy chunks, others shredded mixes. Giving your cat choices can help find a wet food texture they enjoy.

Homemade & Raw Diets

Some cat owners choose to make their own cat food at home or feed raw food diets. There are some potential benefits but also risks to consider with these alternative diets.

Potential benefits of homemade cat food include having more control over ingredients, catering to your cat’s preferences, and avoiding certain additives. However, designing a nutritionally balanced diet takes research and trial-and-error [1]. Common pitfalls include nutritional deficiencies or excesses.

Raw diets aim to mimic a cat’s natural diet prior to domestication. Possible benefits are healthier teeth and gum, better digestion, and shinier coats. However, raw meat carries risks of bacterial contamination like salmonella and E. coli [2]. Handling and storing raw meat properly is crucial.

Overall, homemade and raw diets take dedication to do right. Work closely with your vet to formulate recipes and monitor your cat’s health. For most owners, high-quality commercial cat foods are the safer, more convenient option.

Key Takeaways

When considering the health impacts of dry cat food, there are a few key points to keep in mind:

Dry food is highly processed and contains more carbohydrates than a cat’s natural diet. This can lead to obesity, diabetes, urinary tract diseases, and other problems over time.1 However, dry food is more affordable and convenient for many cat owners.

Wet food has higher protein content and more moisture to support hydration. It may be better for cats prone to urinary problems. But wet food spoils quickly and must be refrigerated once opened.

Homemade and raw food diets allow customization for individual cats. But they require more effort and balanced recipes to provide complete nutrition.

There is no definitive answer on the best cat food type. The optimal diet depends on the individual cat’s health, preferences, and lifestyle factors of the owner. Consult a veterinarian to determine what is best for your cat’s needs.
