- ✓Dry-only diets are a major risk factor for kidney disease — the number one killer of cats over 10.

The best cat food in the UK is Lily's Kitchen for premium wet food (£1.80–£2.50/day), or Royal Canin for breed/health-specific dry food. Cats are obligate carnivores — high meat content and moisture are non-negotiable.
Unlike dogs, cats cannot synthesise several essential nutrients (taurine, arachidonic acid, vitamin A from plant sources) and must consume them from animal protein. This is not a preference — it is a biological requirement. The implications for food choice are significant, and many mass-market cat foods fall short of what feline physiology actually demands.

Wet vs Dry for Cats — The Vet's View
This is the most important decision you will make about your cat's diet, and the evidence is clear: cats benefit significantly from moisture-rich food.
Cats evolved as desert-dwelling predators who obtained nearly all their water from the prey they ate. Unlike dogs, cats have a blunted thirst response — they do not drink enough water to compensate for a dry diet. This leads to chronic mild dehydration, which stresses the kidneys over years and decades.
Chronic kidney disease (CKD) is the number one cause of death in cats over 10 years old. UK vets see it in an estimated 1 in 3 cats over 15. While genetics play a role, diet — specifically chronic dehydration from dry-only feeding — is a major modifiable risk factor. Wet food contains 70–80% moisture compared to 8–10% in dry kibble. The difference over a lifetime is substantial.
Our recommendation: feed wet food as the primary diet, particularly for adult and senior cats. If you choose to feed dry food (for convenience or dental reasons), supplement with wet food at least once daily and ensure multiple fresh water sources are available — ideally a cat water fountain, as cats prefer moving water.
Best Cat Food by Life Stage

| Adult (1–7 years) | Applaws or Purina Pro Plan | James Wellbeloved Adult | Balanced nutrition, high protein, moderate calories |
| Senior (7+ years) | Hills Science Diet 7+ | Royal Canin Ageing 12+ | Kidney support, joint support, easier to chew, high moisture critical |
Our Top Picks in Detail
1. Lily's Kitchen — Best Overall Wet Food
Lily's Kitchen consistently tops our wet food rankings for good reason: 65%+ named meat content, no artificial additives, no meat meal derivatives, and a palatability score that converts even finicky cats. Their recipes use human-grade ingredients and meet the nutritional standards of both FEDIAF and AAFCO. Available in tins and pouches from most UK supermarkets and pet stores. At ~£2.20/day, it is a genuine premium product at a realistic price.
2. Applaws — Highest Meat Content
Applaws is the go-to recommendation for owners who want maximum meat percentage. Their wet tins contain 75%+ named fish or chicken with very minimal other ingredients — often just broth and a small amount of complementary food. Note that Applaws is marketed as a "complementary" food in some formats, meaning it should be rotated with nutritionally complete foods rather than fed exclusively.
3. Royal Canin — Best Breed & Condition Specific
Royal Canin's strength is precision nutrition for specific breeds (Ragdoll, Persian, British Shorthair) and medical conditions (urinary health, gastrointestinal sensitivity, renal support). If your cat has a diagnosed health condition, Royal Canin is often the first-line vet recommendation due to the extensive clinical research backing their formulas. For healthy cats with no specific needs, higher-meat alternatives provide better value.
4. Hills Science Diet — Best for Prescription Conditions
Hills k/d (kidney diet), c/d (urinary), and m/d (metabolic) are prescription ranges with the strongest clinical evidence base for managing feline medical conditions. If your cat has been diagnosed with CKD, struvite/oxalate crystals, or obesity, Hills prescription diets are the gold standard. Available through your vet.
5. Bozita — Best Mid-Range Value
Bozita is a Swedish brand now widely available in the UK via Zooplus and Amazon. Their wet food range offers 45%+ meat content at ~£1.60/day — significantly better value than Lily's Kitchen for those on a tighter budget, while still meeting the high-moisture, high-protein criteria. Their jelly-format pouches are popular with cats who prefer a firmer texture.

❓ Frequently Asked Questions
Is wet or dry food better for cats?
Wet food is generally better for cats. Cats evolved to get most of their moisture from prey and have a naturally low thirst drive. Dry-only diets create chronic mild dehydration, which is a major risk factor for feline kidney disease (CKD) — the leading cause of death in cats over 10. If you feed dry food, supplement with wet at least once daily.
How much should I feed my cat per day?
Most adult cats need 200–250 kcal/day, roughly 2–3 pouches of wet food or 50–60g of quality dry food. Exact amounts depend on weight, age, and activity level. Follow the manufacturer's feeding guide and adjust based on body condition — you should be able to feel your cat's ribs but not see them.
Is grain-free cat food better?
Not necessarily. Cats don't have a metabolic need for grains, but grain-free doesn't automatically mean higher quality. Some grain-free dry foods replace grains with starchy legumes or potatoes. Focus on meat percentage and protein source rather than the grain-free label.
What is the best food for indoor cats?
Indoor cats tend to be less active and prone to weight gain and hairballs. Look for foods with moderate calorie density, added fibre for hairball control, and high moisture. Royal Canin Indoor, James Wellbeloved Indoor, and Hills Science Diet Indoor are all solid options.
What is the best food for an overweight cat?
Choose a high-protein, lower-carbohydrate wet food and reduce portion sizes rather than switching to diet dry kibble. Wet food is more satiating per calorie. Hills Science Diet Perfect Weight and Royal Canin Weight Care are common veterinary weight-management diets. Transition slowly over 7–10 days.
