Feline Nutritional Requirements
Cats are obligate carnivores, meaning they require meat-based proteins to thrive. Unlike dogs, cats cannot synthesise taurine, an essential amino acid found almost exclusively in animal tissue. This fundamental difference shapes what makes a nutritionally complete cat food.
A balanced feline diet should contain approximately 40% protein, 9-15% fat, and less than 10% carbohydrates. Most commercial cat foods meet AAFCO (Association of American Feed Control Officials) standards, which are recognised by the Pet Food Manufacturers' Association in the UK as reliable nutritional benchmarks.
Essential nutrients for cats include:
- Protein: Supports muscle development and immune function
- Taurine: Critical for heart and eye health
- Fat: Provides energy and supports coat health
- Vitamins and minerals: Support bone health and metabolic function
- Water: Especially important for kidney health
Wet vs Dry Cat Food: What's Best?
The wet versus dry debate is one of the most common questions cat owners ask. Both have legitimate advantages depending on your cat's needs and your circumstances.
Dry Cat Food
Advantages of Dry Food
- More economical: typically £0.50-£1.50 per day for quality brands
- Better for dental health through mechanical cleaning action
- Easier portion control and storage
- Longer shelf life after opening
- Convenient for free-feeding and multi-cat households
Disadvantages of Dry Food
- Lower moisture content (10-12%) may contribute to dehydration
- Often contains more fillers and carbohydrates
- Less appealing taste to some cats
- May contribute to urinary issues in susceptible cats
Wet Cat Food
Advantages of Wet Food
- High moisture content (75-80%) promotes hydration
- More palatable and closely resembles natural prey
- Generally higher protein content and lower carbohydrates
- Better for cats with dental issues or sensitive digestion
- Beneficial for urinary tract health
Disadvantages of Wet Food
- More expensive: £2-£4 per day for quality brands
- Once opened, must be used within 24-48 hours
- Requires refrigeration and careful handling
- Can spoil quickly in warm weather
- Less convenient for busy owners
The ideal approach for many vets is a combination: wet food for main meals (providing hydration and nutrition) and high-quality dry food for treats or topping up calories.
Top 10 Cat Food Brands Reviewed
1. Royal Canin
Royal Canin is backed by decades of veterinary research and breed-specific formulations. Their products address specific health concerns like digestive sensitivity, skin health, and weight management. The brand is highly recommended by vets for cats with dietary requirements. Quality ingredients and balanced nutrition make it a premium choice, though not the most budget-friendly option.
2. Hills Science Diet
Hills Science Diet employs rigorous testing and clinical research. Available at most veterinary practices, it's ideal for cats needing therapeutic diets. Their digestive care and senior formulas are particularly well-regarded. Though premium-priced, the consistent quality and veterinary endorsement justify the cost for health-conscious owners.
3. Applaws
Applaws emphasises natural, high-protein ingredients with minimal fillers. Their recipes typically contain 40%+ protein from meat sources. Whilst slightly pricier than mainstream brands, it offers excellent nutritional value. Available at most UK supermarkets and online, making it convenient for regular purchase.
4. Lily's Kitchen
This UK-based brand focuses on human-grade ingredients and ethical sourcing. Their recipes include recognisable meat sources and vegetables. The brand appeals to environmentally conscious owners. While slightly more expensive than economy brands, the quality and values alignment justify the premium for many cat owners.
5. Canagan
Canagan offers grain-free recipes with high meat content (70%+). Their products cater to cats with grain sensitivities or those requiring biologically appropriate nutrition. The brand is popular with owners seeking premium, natural alternatives. Price point sits comfortably between budget and luxury options.
6. Sheba
Sheba is highly palatable and widely available, making it appealing for finicky eaters. However, nutritional value is lower with higher carbohydrate content and less protein than premium brands. The convenient individual pouches suit single cats or those with portion control needs. Better as an occasional treat than daily staple.
7. Felix
Felix is extremely budget-friendly and readily available in every UK supermarket. Whilst palatable to most cats, nutritional profiles are less impressive than premium brands. The variety of flavours appeals to cats that tire of food quickly. Suitable for budget-conscious owners but not ideal as a sole diet.

Whiskas is ubiquitously available and extremely affordable. However, it contains higher grain content and lower meat percentages than nutritionally optimal foods. The marketing heavily targets taste over nutrition. Acceptable for budget-restricted owners but consider supplementing with higher-quality foods when possible.
9. Purina Pro Plan
Purina Pro Plan offers scientifically formulated recipes at reasonable prices. Their range includes therapeutic options for health conditions. Widely available through supermarkets and online retailers, it provides good nutritional value without premium brand pricing. A solid mid-range option for health-conscious budget-aware owners.
10. Iams Proactive Health
Iams provides balanced nutrition at accessible prices. Their formulas address common health concerns like hairball reduction and weight management. Readily available across the UK, it offers decent value without premium pricing. Suitable for owners seeking quality above budget brands but below luxury options.
How to Read Cat Food Labels
Understanding cat food labels empowers you to make informed choices. In the UK, pet food is regulated by the Pet Food Regulations 2011, requiring clear ingredient declarations.
Key Label Information
Crude Protein: Look for at least 30% for adult cats, 40%+ for premium quality. Higher percentages indicate more nutritious food.
Crude Fat: Optimal levels are 9-15%. Fat provides essential fatty acids and energy.
Crude Ash: This represents mineral content. Lower ash content (under 8%) is preferable, especially for cats prone to urinary issues.
Fibre: Cats require only 1-3% fibre. Higher levels suggest more fillers and less digestible ingredients.
Taurine: The label should explicitly list taurine supplementation. This is non-negotiable for health.
Ingredient Order Matters
Ingredients are listed by weight. Foods listing meat as the first ingredient contain more meat than those with grains listed first. Be wary of foods where corn, wheat, or soy feature prominently in the first five ingredients.
Feeding Schedules by Age
Kittens (8 weeks to 6 months)
Kittens require more frequent feeding and higher protein content (40%+) for growth. Feed kitten-specific formulas three to four times daily. Portion sizes typically follow manufacturer guidelines: roughly 30-50g per 500g of body weight daily, divided into multiple meals.
Young Adults (6 months to 1 year)
Transition to twice-daily feeding as growth slows. Continue kitten formula until 12 months for proper development. Gradually introduce adult food near the one-year mark over 7-10 days to avoid digestive upset.
Adult Cats (1 to 7 years)
Most adult cats thrive on twice-daily feeding: morning and evening meals. Average daily intake is 150-250 calories depending on size and activity level. Use the body condition score (visible ribs, defined waist when viewed from above) to adjust portions.
Senior Cats (7+ years)
Senior cats may benefit from more frequent, smaller meals if they experience decreased appetite. Consider foods with enhanced joint support (glucosamine) and antioxidants. Wet food becomes increasingly important for hydration as kidney function declines with age.
Special Dietary Needs
Urinary Tract Health
Cats prone to urinary issues benefit from high-moisture, low-ash diets. Wet food is significantly better than dry for preventing urinary blockages. Ensuring adequate water intake through food is important. Hill's c/d and Royal Canin Urinary are specifically formulated for this concern.
Sensitive Digestion
Cats with food sensitivities or digestive issues need limited ingredient diets with easily digestible proteins. Chicken and fish are common proteins; some cats benefit from novel proteins like venison or duck. Hill's Science Diet Sensitive Skin and Stomach is widely recommended for sensitive cats.
Weight Management
Overweight cats require controlled portions and increased exercise. Weight management formulas typically contain less fat and more fibre to promote satiety. Portion control is often more important than food choice; measure portions carefully and resist begging.
Kidney Disease
Senior cats and those with kidney disease benefit from controlled protein and phosphorus. Prescription diets like Hill's k/d or Royal Canin Renal Support are specifically formulated to support kidney function and manage disease progression.
Budget vs Premium: Is It Worth It?
Premium cat foods cost 50-100% more than budget brands, but do they deliver proportional benefits? The answer is nuanced.
Budget brands typically contain more fillers, lower digestibility, and less meat. Your cat may require larger portions to feel satisfied, potentially offsetting cost savings. Premium brands often result in smaller, less frequent stools due to superior digestibility.
For healthy adult cats without sensitivities, mid-range brands (£12-£15/kg) offer excellent balance between quality and cost. For senior cats, those with health issues, or finicky eaters, premium brands justify the investment.
Switching Foods Without Upset Stomachs
Abrupt food changes often cause vomiting and diarrhoea. Follow this gradual transition protocol over 7-10 days:
- Days 1-2: Mix 25% new food with 75% old food
- Days 3-4: Mix 50% new food with 50% old food
- Days 5-6: Mix 75% new food with 25% old food
- Days 7-10: Transition to 100% new food
If digestive upset occurs, slow the transition further. Some cats require 2-3 weeks for complete transition. If vomiting or severe diarrhoea persists, consult your vet as your cat may have a genuine food intolerance.

Frequently Asked Questions
Unless your cat has a diagnosed grain allergy, grain-free food offers no additional benefit. Many grain-free foods substitute grains with other carbohydrates like potatoes. If your cat tolerates grains, grain-inclusive foods with quality meat sources are perfectly adequate. Focus on protein content and ingredient quality rather than grain-free status.
Whilst some owners feed raw diets, they pose bacterial contamination risks (salmonella, E. coli) for both cats and humans. Raw diets also risk nutritional imbalances if improperly formulated. Commercial raw food products are more controlled but remain expensive. Consult your vet before attempting home-prepared raw diets.
Finicky eating often develops from early exposure to highly palatable low-quality foods. Gradual transition to healthier options combined with patience may help. Warming wet food to room temperature increases palatability. Never force food; remove uneaten portions after 20 minutes to avoid contamination. Consult your vet if your cat refuses food for more than 24 hours, as cats can develop hepatic lipidosis.
Complete and balanced commercial cat foods contain all necessary vitamins and minerals. Supplementation is unnecessary unless your vet recommends specific supplements for a health condition. Over-supplementation can cause toxicity, particularly with fat-soluble vitamins (A, D). Always consult your vet before adding supplements.
Kitten formulas contain higher protein (40%+), fat, and essential nutrients for growth and development. Adult foods are formulated for maintenance. Feeding kitten food to adult cats can lead to obesity and nutritional imbalances. Conversely, feeding adult food to kittens may stunt growth. Use age-appropriate formulas for optimal health.
If your cat is healthy and thriving, there's no need to frequently switch brands. Consistency aids digestive health. That said, occasionally rotating brands (every few months) can prevent food aversions and ensure nutritional variety. Any changes should follow the gradual 7-10 day transition protocol.
