Cats age gracefully, but their bodies do change, and what's in the bowl should change with them. If your cat is heading into their later years, you might be wondering whether they need special food, more protein or less, and what to do when they start picking at their dinner. Here's the up-to-date, vet-informed answer, including one big myth that trips up a surprising number of owners.
When is a cat actually a senior?
There's no single birthday that flips the switch, but vets do use clear life stages to guide care. Under the 2021 AAHA/AAFP feline life stage guidelines, a cat is a "mature adult" from 7 to 10 years, and a "senior" once they're over 10 (Quimby et al., 2021). That's why you'll often see food labelled "senior 7+", catching cats as they enter that mature phase and their needs start to shift.
The honest truth, though, is that ageing shows up differently in every cat. Some 12-year-olds bounce around like kittens, while others slow down earlier. So it's less about the number on the calendar and more about the cat in front of you. If you've noticed changes, it's worth thinking about their diet, and you can browse recipes made for this stage in our senior dry cat food range.
How your cat's needs change as they age
A few things quietly shift as cats get older, and understanding them makes everything else make sense:
-
Muscles naturally thin. Cats gradually lose lean muscle with age, a process called sarcopenia (essentially age-related muscle loss). Holding on to that muscle becomes a real priority (Laflamme & Gunn-Moore, 2014).
-
Digestion becomes less efficient. Many older cats absorb protein and fat less well than they used to, so they need food that's high quality and easy to digest to get the same goodness from it (Laflamme & Gunn-Moore, 2014).
-
Weight can drift either way. Some seniors gain weight as they slow down, while others, especially the very old, start to lose it.
-
The body changes. Teeth, kidneys, joints and even their sense of smell can all change with age, and each of those can affect how, and how much, your cat wants to eat.
None of this is cause for alarm. It just means a little thought about their food goes a long way. Our recipes are developed with veterinary input from Dr Scott Miller, with exactly these later-life changes in mind.
Do senior cats need more or less protein?
This is the big one, and it's where a lot of older advice gets it backwards. For years the received wisdom was that senior cats need less protein, usually out of worry about their kidneys. For healthy older cats, the opposite is generally true.
Because ageing cats are losing muscle and digesting less efficiently, healthy seniors often need more good-quality protein, not less, to hold on to lean body mass and stay strong (Laflamme & Gunn-Moore, 2014). Cutting protein in a healthy senior can actually speed up that muscle loss.
So where did the low-protein idea come from? It's relevant for specific diagnosed conditions, most notably advanced kidney disease, where a vet may recommend a carefully controlled diet. The key word is diagnosed. Protein restriction is a medical decision for particular cats, made with your vet, never a blanket switch every older cat needs (Quimby et al., 2021). For a healthy senior, a recipe rich in quality animal protein is usually exactly what they want. You'll find that in our senior dry cat food and across our wet cat food recipes.
Wet, dry or a bit of both?
Both have a place, and for older cats the case for including some wet food gets stronger.
-
Hydration matters more with age. Kidneys have to work harder as cats get older, and the extra moisture in wet food is a gentle way to help keep them topped up, which supports kidney and urinary health.
-
Soft textures suit sore mouths. Dental trouble is common in older cats, and soft, easy-to-eat wet food is kinder to tender teeth and gums.
-
Dry food has its uses too. It's convenient, easy to store, and handy to leave out for a cat who prefers to graze across the day.
-
Mixing gives you the best of both. Many older cats do well on a combination, getting moisture from wet food and the convenience of dry.
One simple trick helps enormously: gently warming wet food to just warm to the touch wakes up its aroma, which is a real boost for an older cat whose sense of smell has faded a little. You can explore textures across our wet cat food and senior dry cat food recipes.
Feeding a cat with a health condition
Older cats are more prone to certain conditions, and several of them are managed partly through diet. The common ones include:
-
Kidney disease, where a vet may advise a diet with controlled protein and phosphorus (phosphorus is a mineral that healthy kidneys clear from the blood)
-
An overactive thyroid (hyperthyroidism), which can drive up appetite while a cat still loses weight
-
Diabetes, which often calls for a specific dietary approach
-
Arthritis, where keeping a cat at a healthy weight eases the load on sore joints
-
Dental disease, which can make eating uncomfortable
Here's the important part: these conditions usually call for a specific or prescription diet chosen with your vet, not a do-it-yourself switch to low-protein food. A prescription diet is one formulated for a diagnosed medical condition and recommended by your vet, and it's the right tool when it's genuinely needed. If you suspect any of these, a vet visit comes first. Our Dr Scott Miller would always say the same: diagnose, then feed accordingly.
When your older cat goes off their food
It's fairly common for an older cat's appetite to dip a little, partly because a fading sense of smell makes food less exciting. A few gentle tweaks often help:
-
Warm their food slightly to bring out the aroma
-
Offer smaller meals more often rather than one big bowl
-
Use a clean, shallow bowl, raised slightly if your cat has a stiff neck or achy joints, so they don't have to crouch
That said, there's a firm line worth knowing. A sudden drop in appetite, or a cat who won't eat at all, is not something to wait out, because cats shouldn't go long without food. If your older cat goes off their dinner suddenly or for more than a day, call your vet. For the full toolkit on tempting a choosy eater, we've gone deeper in our guide to why your cat might be a fussy eater.
Keeping them at a healthy weight
Weight is worth watching closely in later life, and it can go both ways. Some seniors quietly lose muscle while gaining fat, so they can look an "okay" size while actually losing condition. Others lose weight noticeably as they get very old.
A few sensible habits:
-
Keep half an eye on their shape and how they feel under your hands, not just the number on the scales
-
Feed to the cat in front of you, using the pack guide as a starting point and adjusting to how they're doing
-
Treat any unexpected weight loss as a reason for a check-up, not something to ignore
Weight gain matters too. An estimated 43% of UK cats are overweight or obese, which adds strain to ageing joints and organs (PDSA, 2024). If your senior is carrying a bit too much, a lighter recipe like Fat Cat Slim can help, ideally guided by your vet.
Our senior-friendly recipes
When it comes to what we'd actually reach for, Senior Moments is our dry recipe made just for older cats. It's built around salmon and chicken, grain-free and gentle on digestion, with added taurine (an essential nutrient for a healthy heart and eyes) plus glucosamine and chondroitin to help support ageing joints. Like everything we make, it's natural, vet-approved and free from artificial colours, flavours and preservatives.
For cats who fancy something softer and especially tempting, our high-meat wet cat food recipes are easy to eat and full of aroma, which is just the ticket for an older cat who needs a little encouragement. You can see the full later-life selection in our senior dry cat food range.
We'd never claim one recipe is right for every cat. The best food is the one that suits your individual senior, their health and their tastes, ideally with a steer from your vet.
Feeding a senior cat well isn't complicated once you know the key point: most healthy older cats need more good-quality, easily digestible protein, not less, to stay strong and well. Keep an eye on their weight and appetite, lean on wet food for hydration and tempting aromas, and always let your vet lead if a health condition is in the picture. Do that, and you'll help your cat enjoy their later years in great shape, with extra love and care in every bowl.
You'll find recipes made for this stage in our senior dry cat food range, including Senior Moments.
FAQs
At what age is a cat a senior?
Vets generally consider cats "mature" from 7 to 10 years and "senior" once they're over 10, though many foods are labelled "senior 7+". Ageing varies a lot between cats, so it's about the individual rather than a fixed birthday.
Do senior cats need special food?
Often, yes. Senior recipes are designed to be easy to digest and rich in quality protein to help maintain muscle as cats age. A complete senior food is a sensible choice for most healthy older cats.
Is wet or dry better for older cats?
Both work, and many older cats do best on a mix. Wet food adds valuable moisture, which helps as kidneys age, and suits sore mouths, while dry is convenient for grazing.
Do older cats really need less protein?
Usually the opposite. Healthy senior cats often need more good-quality protein to hold on to muscle. Protein is only restricted for cats with certain diagnosed conditions, such as advanced kidney disease, and always on a vet's advice.
Why has my senior cat lost weight or gone off their food?
A little gradual change can be normal with age, but sudden weight loss or a real drop in appetite can signal a problem like dental disease, kidney disease or an overactive thyroid. It's best to see your vet promptly.
Should I warm my older cat's food?
It can really help. Gently warming wet food to just warm to the touch releases more aroma, which is appealing for older cats whose sense of smell has dulled. Always stir well and never serve it hot.
Can a senior cat eat normal adult food?
A healthy cat can, but a senior recipe is formulated for their changing needs, with easily digestible, quality protein to support muscle. If your cat is well and happy on their adult food, chat to your vet about the best time to switch.
How often should I feed an older cat?
Smaller, more frequent meals often suit older cats, especially if their appetite has dipped. Follow the guide on the pack as a starting point and adjust to your individual cat, with your vet's input if needed.
