Cat Food Guide: Wet vs Dry, Diet Advice & Top UK Picks

Choosing the right food for your feline friend can be overwhelming with so many options out there—wet, dry, raw, prescription, and more. In this guide, we’ll break down the different types of cat food, what’s best for kittens vs adult cats, and help you decide between wet and dry food based on your cat’s needs. Whether you're looking for healthy cat food in the UK or wondering how much wet food to feed, we've got you covered.

Why Your Cat’s Diet Matters

Just like humans, cats need a balanced diet to stay healthy and maintain an ideal weight. When choosing cat diet food, it’s important to understand the difference between complete and complementary options—complete cat food provides all the essential nutrients your cat needs daily, while complementary foods (often treats) should only be given occasionally, as they can unbalance your cat’s nutrition and lead to weight gain. Your cat’s dietary needs also vary depending on age, breed, and activity level—kittens need energy-dense food for growth, senior cats benefit from joint-supporting, lower-calorie diets, and active outdoor cats require more calories than indoor ones. When selecting healthy cat food in the UK, consider not just nutrients but also factors like hydration wet food can support urinary health—and dental care, as some dry foods help reduce plaque. Prioritizing complete, well-formulated cat food ensures your feline stays healthy, hydrated, and happy.

Types of Cat Food Explained

Cats are obligate carnivores, meaning they need meat in their diet to survive, so choosing the right type of cat food is vital for their health and wellbeing. There are several types of cat food available dry, wet, semi-moist, homemade, and even specialized options like raw, freeze-dried, and prescription diets—each with distinct benefits and drawbacks.

Dry Cat Food (Kibble)

Among the most popular types of cat food, dry cat food—commonly known as kibble—is favored for its convenience, affordability, and long shelf life. It is easy to store and feed, making it ideal for busy pet owners. Dry food also offers the added benefit of helping to reduce plaque buildup on your cat’s teeth, promoting better dental health. However, one drawback is its low moisture content. Since many cats don’t drink enough water on their own, a kibble-only diet can lead to dehydration or urinary tract issues. Additionally, dry food often contains higher levels of carbohydrates, which may not be suitable for overweight or diabetic cats.

Wet Cat Food (Canned Food)

Wet cat food is another widely used option and is especially beneficial for cats that need more hydration in their diet. With high moisture content and a texture that closely resembles meat, wet food is more appealing in taste and aligns more naturally with a cat's carnivorous instincts. It typically contains higher protein and lower carbohydrate levels than kibble, making it one of the healthier types of cat food for many cats. However, it has its downsides—wet food is more expensive, spoils quickly once opened, and can be messy to serve and store. It may also contain preservatives, so it’s important to read ingredient labels carefully.

Semi-Moist Cat Food

Semi-moist cat food offers a middle ground between dry and wet varieties. Soft and chewy in texture, it is convenient to feed and often comes in single-serving pouches, making portion control easy. It’s among the less common types of cat food, but some owners choose it for its palatability and ease of use. However, semi-moist foods are typically more expensive than dry food and may contain added sugars and artificial flavors to enhance taste, which may not be ideal for cats with health concerns. While convenient, it’s not always as nutritionally balanced as high-quality dry or wet foods.

Homemade Cat Food

Homemade cat food is becoming increasingly popular among pet owners who want full control over what their feline eats. This type of diet involves preparing meals using fresh, whole ingredients at home, allowing customization based on your cat’s specific dietary needs. Of all the types of cat food, homemade diets offer the greatest flexibility in ingredient choice and quality. However, they come with significant challenges—they are time-consuming to prepare, more expensive, and, if not properly balanced, can lead to nutritional deficiencies. Consulting a veterinarian or a certified pet nutritionist is essential before switching to a homemade diet to ensure your cat receives all necessary nutrients.

Wet vs Dry Food: Which Is Better?

The key differences between wet and dry cat food, includes pros and cons, vet-approved insights, and answers common questions—optimized with your keywords:

When choosing between wet and dry food for your cat, the decision can feel overwhelming. Both types have their own benefits and drawbacks, and the best choice often depends on your cat’s specific health needs, lifestyle, and preferences.

Moisture Levels: A Key Difference

The most noticeable difference is water content:

• Dry Cat Food: Contains around 10% moisture and 90% dry matter (carbs, fats, protein, vitamins)

• Wet Cat Food: Contains approximately 70% moisture, making it more hydrating.

Manufacturing Process

• Wet Food: Made from fresh or frozen meats blended with water, vitamins, and fats, then sealed and heat-processed to destroy pathogens

• Dry Food: Ingredients are cooked under high pressure and temperature to make starches digestible. Fat is often sprayed on afterward for taste.

Nutrient Comparison

• Dry Food: Often higher in carbohydrates and may include added probiotics.

• Wet Food: Usually contains higher levels of animal-based proteins and fewer carbs, which aligns more closely with a cat’s natural diet.

Do Cats Need Wet Food Every Day?

Cats are notoriously picky drinkers—and there’s a reason for it. In the wild, felines instinctively avoid still or standing water, as it can be a source of bacteria and insects. This natural aversion often carries over to domestic cats, making them reluctant to drink from bowls or dishes.

Why Cats Don't Drink Much Water

Many cats prefer fresh, moving water, such as from a faucet or cat water fountain. Drinking is not an efficient process for them either—a single lap delivers only about 3/100 of a teaspoon of water. On top of that, cats often feel vulnerable while drinking, which can add to their hesitancy. But despite their preferences, water is crucial. It makes up about 60% of your cat’s body, playing a vital role in:

• Chemical reactions and metabolism

• Temperature regulation

• Joint health and mobility

Hydration Benefits of Wet Cat Food

One of the best ways to help your cat stay hydrated—especially if she’s not a frequent drinker—is by feeding wet cat food.

• Moisture Content: Wet food contains around 70% water, compared to just 10% in dry kibble.

• Supports Kidney and Urinary Health: Especially important for older cats or those prone to urinary tract issues.

• Encourages Natural Hydration: Wet food mimics the moisture content of a cat’s natural prey in the wild.

While wet food can’t replace water entirely, it goes a long way in boosting daily hydration.

When to Prioritise Wet Over Dry

You might consider switching to (or incorporating) wet food if your cat:

• Suffers from kidney disease, UTIs, or bladder stones

• Shows little interest in drinking water

• Eats mainly dry food but has recurring digestive issues

• Is a senior cat with mobility issues that limit access to water bowls

Kitten Nutrition: Special Considerations

Kittens are bundles of energy and curiosity—but behind all that playfulness is a growing body with very specific nutritional needs. Choosing the best kitten food means understanding how it differs from adult cat food and what type (wet or dry) is best suited for your young feline. Kittens grow rapidly during their first year of life, and their diet needs to support that development. Here’s how kitten food differs from adult cat food:

Can Cats Live on Dry Food Alone?

While dry cat food can provide complete and balanced nutrition, it's important to understand the long-term implications of feeding only dry food especially when it comes to hydration and overall health, dry food can be a healthy choice. Look for formulas that:

• List real meat (like chicken, turkey, or fish) as the first ingredient

• Contain minimal fillers like corn or soy

• Include added taurine, omega fatty acids, vitamins, and minerals

Cats are obligate carnivores, meaning their diet must be meat-based. Some dry foods are better formulated than others, so choosing a premium brand is key to ensuring your cat gets the nutrition they need.

Final Thoughts: Choosing the Best Food for Your Cat

When it comes to selecting the right food for your feline companion, it's essential to understand the different types of cat food and how they can meet your cat's specific needs. Dry cat food is convenient and helps with dental health but may lead to dehydration and contains higher carbs. Wet cat food, with its high moisture content, is great for hydration and protein but spoils quickly and can be messy.

Semi-moist food offers a balance between dry and wet, though it tends to be pricier and sometimes less nutritionally complete. Homemade cat food gives you full control over ingredients but can be time-consuming, costly, and requires careful balancing to ensure nutritional adequacy. Each type has its pros and cons, and the best option will depend on your cat’s lifestyle, age, and health conditions.

Tailoring your choice to your cat’s specific needs is crucial—kittens, seniors, and active cats may require different nutritional profiles. Likewise, if your cat has health issues like obesity or diabetes, certain foods may be more beneficial than others. Always consult with your vet to ensure you're meeting your cat’s unique dietary requirements.
