Best Cat Food (2026): UK Wet, Dry, Kitten & Senior Food Tested
Our top picks at a glance
What to look for in cat food
Every cat is an individual, but the basics of good cat food do not change. Cats are obligate carnivores: they need animal protein, taurine (which is only found in animal tissue) and the right balance of vitamins, and they cannot survive on a vegetarian diet. The most important things to check on any label are that it is complete and balanced for your cat's life stage, that a named animal protein is the first ingredient, and that it comes from a manufacturer with proper quality control.
Price per kilo is a useful sanity check: genuinely premium food costs more, but paying extra for marketing fluff is pointless when a mid-range complete food from a trusted brand will do the same job. Where you should spend more: kittens, seniors, and cats with diagnosed health conditions (urinary, allergies, sensitive digestion). For a healthy adult cat, the best food is the one it will actually eat consistently - a fussy cat that refuses premium food is better off on the mid-range option it finishes.
The 8 best cat foods (2026)
1. Best wet food: Whiskas Adult Wet Cat Food in Jelly 40x85g Poultry Feasts
~£12.49
Whiskas is the wet food most UK cats will actually eat, and this 40-pouch poultry box is the best-value way to buy it. Each 85g pouch is a complete, balanced meal with tender chicken or turkey pieces in jelly, and the texture suits cats that turn their nose up at pate. Buying the bulk box works out well under 35p a pouch versus 60p+ for singles, which matters when a cat eats two pouches a day. It is not the premium choice on this list, but for fussy eaters and multi-cat homes it is the most reliable daily wet food we have tested.
2. Best dry food: PURINA ONE Adult Dry Cat Food, Chicken 7.5kg
~£29.99
Purina ONE is the dry food vets most often recommend as a complete everyday diet, and this 7.5kg bag is the best value per kilo on the market. It is high in animal protein with chicken as the first ingredient, includes omega-6 for skin and coat, and has no artificial colourings or preservatives. The larger kibble size encourages chewing, which is good for dental health. A 7.5kg bag lasts a single adult cat roughly three months, making this the cheapest complete nutrition you can buy without dropping to own-brand quality.
3. Best senior food: FELIX As Good As It Looks Senior 7+ in Jelly 12x85g
~£4.50
Older cats lose appetite and muscle, so senior food needs to be soft, appetising and slightly higher in the nutrients ageing kidneys and joints need. Felix Senior 7+ delivers that in the most palatable format we tested - tender meat in jelly that arthritic or dental-problem cats can eat without pain. This 12-pouch tray is a great way to try it, and the recipe is complete and balanced for cats aged 7 and over. Pair with a senior dry food and you have a practical, affordable plan for an older cat.
4. Best kitten food: FELIX As Good As It Looks Kitten Mixed Selection 40x85g
~£12.95
Kittens grow fast and need calorie-dense, calcium-balanced food in a texture tiny teeth can manage. Felix Kitten Mixed Selection gives you 40 pouches of soft meat in jelly with DHA for brain and eye development, formulated for the first 12 months. The small pieces and strong aroma make weaning straightforward, and the variety pack stops a kitten from fixating on one flavour and refusing everything else later. At under £13 for 40 pouches it is the most economical way to feed a growing kitten properly.
5. Best urinary health: PURINA ONE Urinary Health Chicken Dry 4x750g
~£17.51
Urinary issues are one of the most common reasons cats end up at the vet, and diet is the first line of defence. Purina ONE Urinary Health is a maintenance diet that supports a healthy urinary pH and dilution, reducing the risk of crystals and blockages in at-risk cats. This 4-pack of 750g bags is more economical than the single bag and keeps the food fresh. It is a maintenance diet, not a treatment - if your cat has had a blockage, use the prescription range your vet specifies, then switch to this to keep it healthy.
6. Best sensitive stomach: IAMS Sensitive Digestion Turkey Dry 3kg
~£10.69
For cats with soft stools, vomiting or itchy skin, a sensitive-stomach diet with a single novel protein source and prebiotics often sorts things out. IAMS Sensitive Digestion uses turkey, which is less common in cat diets than chicken, plus prebiotics (FOS) to feed good gut bacteria and beet pulp for fibre. Most owners we spoke to saw firmer stools within two weeks. At 3kg for around £10 it is the most affordable sensitive-stomach diet available in the UK, and it is complete and balanced for adult cats.
7. Best grain-free: Scrumbles Hypoallergenic Chicken & Salmon 750g
~£4.75
Scrumbles is a genuinely grain-free, high-meat recipe at a price that is hard to believe - 74% chicken and salmon with no grain, no sugar and no artificial anything. It is made in the UK, approved by veterinary nutritionists, and the small batch cooking keeps the protein quality high. The hypoallergenic angle means it suits cats with mild grain sensitivities, and the packaging is plastic-free. At £4.75 for 750g it is cheaper than most premium brands and punches well above its weight.
8. Best hypoallergenic (vet): Royal Canin Veterinary Hypoallergenic 400g
~£14.56
If your vet has diagnosed a food allergy, Royal Canin Veterinary Hypoallergenic is the gold-standard elimination diet. The protein is hydrolysed - broken down into fragments too small for the immune system to react to - which makes it the safest diet for cats with suspected allergies. This 400g pouch is the right size to run a proper elimination trial, which should always be done under veterinary guidance. It is expensive per kilo, but for an allergic cat it is cheaper than repeated vet visits and miserable scratching.
Frequently asked questions
How much should I feed my cat per day?
An average adult cat needs roughly 40-50g of dry food or 2-3 pouches of wet food per day, split into two meals. Kittens need up to four meals a day, and seniors often eat less but need higher-quality protein. Check the feeding guide on the pack and adjust by body condition - you should be able to feel ribs without seeing them. If in doubt, ask your vet at their annual check.
Wet or dry cat food: which is better?
Both have a place. Wet food provides hydration (important because cats naturally drink little and are prone to urinary issues) and is closer to their natural diet. Dry food is more economical, better for dental health and easier to leave out. Most vets recommend a mix: wet food as the main meals plus a measured amount of dry food, with fresh water always available.
How do I switch my cat to a new food?
Cats are creatures of habit and sudden changes cause vomiting or diarrhoea. Transition over 7-10 days: start with 25% new food mixed with 75% old, then 50/50, then 75/25, before going fully to the new food. Keep the same feeding times, and if your cat refuses food for more than 24 hours at any point, slow the transition down.
