Your cat might be a little greyer around the whiskers and a lot keener on the sunny spot by the window, but they're still the boss of the house. As they get older, what's in their bowl matters more than ever. Here's how to choose the best senior cat food for your cat, and why the right answer for one older cat can be the opposite for another.
What's the best senior cat food?
The best senior cat food is a complete recipe built around good-quality meat or fish, with easily digested ingredients, omega-3 fatty acids, and joint-supporting extras like glucosamine, matched to your cat's own weight, muscle, and health. There isn't one "best" food for every older cat. A slightly chunky nine-year-old and a 15-year-old who's getting bony need quite different things.
For most healthy older cats, here's where we'd start:
You'll find our dry recipe for older cats in the senior dry cat food collection, and pouches in our wet cat food collection.
What age is a senior cat?
It depends who you ask, as vets use slightly different stages:
-
The 2021 AAHA/AAFP guidelines (from US vet associations) call cats aged seven to 10 "mature adults", and cats over 10 "seniors" (Quimby et al., 2021).
-
International Cat Care, the UK cat welfare charity, calls cats "mature" from seven, "senior" from 11 to 14, and "super senior" from 15 (iCatCare, 2025).
So most cats count as seniors somewhere between 10 and 11, with changes often starting a few years earlier. The median lifespan of UK cats seen by vets in one large study was 14 years, and plenty live much longer (O'Neill et al., 2015).
Wondering how old your cat is in human years? iCatCare suggests the first two years equal 24 human years, then each year after that adds four:

Not every senior cat needs fewer calories
Many owners assume an older cat needs a lighter diet. For some, that's true. For others, it's the opposite.
A 2025 study from the University of Liverpool followed 209 pet cats aged roughly seven to 16 for up to seven years (Pye et al., 2025). The researchers found that:
-
Muscle loss started early, before cats even reached middle age.
-
Weight crept up slightly between about seven and 10, then started to fall.
-
Body condition dropped after about 10 and a half.
-
By 14, cats were more likely to be underweight than obese.
-
Cats that developed long-term illnesses showed a bigger decline in weight, body condition, and muscle.
Older cats can also find their food harder to digest, and their energy needs may start to rise again from around 12 to 14 years old (Canadian Veterinary Medical Association, 2023).
What this means for you: pick food for the cat in front of you, not just the number on their birthday card.
-
Mature and a little heavy? A recipe designed for weight management, like Fat Cat Slim, may suit them better. Our guide to overweight cats has more on this.
-
Older and getting lighter? They may need tasty, easily digested food that's packed with good-quality protein, and a chat with your vet.
How to check your cat's muscle at home
Weighing your cat tells you part of the story. Checking their muscle tells you the rest, as a cat can carry a little extra fat while still losing muscle underneath.
Vets use a muscle condition score, which grades muscle from normal to severely wasted by feeling areas like the spine, shoulder blades, skull, and hips (Canadian Veterinary Medical Association, 2023). You can do a simple version at home:
-
Run your hand along their spine. You should feel a gentle cushion of muscle on either side, rather than sharp, bony ridges.
-
Feel their hips and back legs. Hollows or a "bony bottom" can be an early sign of muscle loss.
-
Weigh them once a month on the same scales, and jot it down. Small, steady drops are easy to miss by eye.
-
Notice how they move. Hesitating before a jump, or choosing lower perches than before, can go hand in hand with losing muscle in the back legs.
If you notice changes, mention them to your vet. The Liverpool researchers highlighted how useful it is to track weight, body condition, and muscle together as cats age (Pye et al., 2025).
What a senior cat diet needs
A good senior cat diet is about quality and digestibility. These are the things worth looking for:
-
Good-quality protein: older cats still need plenty of protein from meat and fish to help maintain muscle. Protein should only be reduced if your vet advises it for a specific health condition.
-
Easily digested fats: fats are a concentrated source of energy, which can help older cats with smaller appetites.
-
Omega-3 fatty acids: fish like salmon are naturally rich in omega-3s, which may help support joints and a healthy coat.
-
Joint-supporting ingredients: glucosamine and chondroitin are natural building blocks of cartilage (the cushioning in joints), and are often added to senior recipes to help support mobility.
-
Taurine: an amino acid cats need from their food, which can help support healthy eyes and a healthy heart.
-
L-carnitine: a nutrient that helps the body use fat for energy.
Always choose a food labelled "complete", meaning it's designed to be fed on its own without anything extra apart from fresh water.
Wet or dry food for older cats?
Both can work, and many owners use a mix. Each has something to offer an older cat:
-
Wet food adds water to your cat's day, has a strong meaty aroma that can tempt a fading appetite, and is soft for sore or missing teeth.
-
Dry food is easy to measure, stays fresh in the bowl, and is handy for cats who like to graze.
If chewing is getting tricky, iCatCare suggests adding a little water to food and mashing it (iCatCare, 2025). If you're mixing wet and dry, think of it as one daily allowance split between the two, and use the feeding guide on each pack.
Why kidney health matters as cats age
Kidney problems are common in older cats. In a study of over 4,000 cats seen by UK vets, kidney disorders were the most common cause of death in cats aged five and over, accounting for 13.6% (O'Neill et al., 2015).
There's plenty you can do to look after your cat:
-
Keep water easy to find. iCatCare recommends several water bowls around the home, away from food bowls (iCatCare, 2025).
-
Add some wet food, as it's an easy way to add moisture to the day.
-
Book regular check-ups. Your vet can spot early changes with simple blood and urine tests.
-
Leave special diets to your vet. If your cat is diagnosed with kidney disease, your vet may recommend a specific diet. That's a decision for them, not something to try at home.
Drinking a lot more than usual, weight loss, or changes in the litter tray are all worth a call to your vet.
Making mealtimes easier for older cats
Small changes can make a big difference to an older cat's dinner. These tips come from iCatCare (2025):
-
Offer small meals more often, starting with around four to six a day.
-
Warm wet food gently to just below body temperature, as aroma helps tempt older noses.
-
Raise the bowl a little for cats with stiff joints, so they don't have to crouch.
-
Feed in a quiet spot where they won't be disturbed by other pets.
-
Try a wide, shallow bowl, which some cats find more comfortable to eat from.
-
Give a little encouragement. Gentle stroking, chatting, or offering food from your hand can help a reluctant eater.
-
Clear away uneaten wet food after about an hour.
If your older cat has suddenly gone off their food, speak to your vet first. For everyday pickiness, our guide to why your cat is a fussy eater has more ideas.
When you're changing your cat's food, take it slowly. We always recommend switching over a 2 week period starting with 10% new food, 90% current food, and gradually increasing the new food.

FAQs
Is senior cat food worth it?
It can be, especially as your cat's needs change. Senior recipes are designed with older cats in mind, often with joint-supporting ingredients and easily digested proteins. If your older cat is healthy and doing well on a complete adult food, there's no rush to switch, but it's worth reviewing at their next check-up.
What food do vets recommend for senior cats?
Vets generally recommend a complete food that suits your cat's weight, muscle condition, and health, rather than one particular brand. Cats with conditions like kidney disease may need a specific diet from your vet. All our recipes, including Senior Moments, are vet-approved.
Why do old cats get bony?
Older cats tend to lose muscle as they age, and some find it harder to digest their food. Weight loss can also be a sign of health problems like an overactive thyroid or kidney disease, so a vet check is a good idea if your cat is getting thinner.
What's the average lifespan of a cat in the UK?
In a large study of cats seen by UK vets, the median lifespan was 14 years (O'Neill et al., 2015). Many cats live well into their late teens, especially with regular vet care and a diet that suits them.
Can an older cat eat kitten food?
Kitten food is designed for growth, so it isn't usually the right everyday choice for a healthy older cat. If your senior cat is losing weight and needs extra energy, your vet can advise on the best way to help.
How much should a senior cat eat?
It depends on your cat's weight, muscle, activity, and health. Start with the feeding guide on the pack or the feeding calculator on our product pages, weigh your cat monthly, and adjust with your vet's help if they're gaining or losing weight.
