Cats are experts at hiding pain, so the signs that something is wrong in an older cat are usually quiet ones.

The clearest signal many owners miss, or misread, is a change in toileting. A cat that suddenly pees on the bed or the floor after years of perfect litter habits could mean something is wrong, physical or emotional, and either way, it needs attention.

Cats are generally considered senior from around seven. From then, the signs of a problem tend to be subtle rather than dramatic. Knowing what to watch for helps you catch them early, when they are most treatable.

I'll cover the quiet signs worth watching, the kidney link every owner should know, the one symptom that is a genuine emergency, and how to support an aging cat day to day.

This article was created in partnership with Royal Canin.

Cats hide illness, so the warning signs are quiet. Learn your cat's normal and act on small changes.
A cat suddenly toileting outside the litter tray is telling you something is wrong, not misbehaving.

5 Quiet Signs Worth Watching

Most senior cat problems show up as small changes in everyday habits, not dramatic symptoms.

The five to watch are eating, drinking, toileting, weight, and how they move. Each one tells you something when it shifts. Your cat might drink more than usual, slowly lose weight, or go off their food. They might move more stiffly, or change how and where they toilet.

Toileting is often the loudest of these signs. Watch for going outside the tray, straining, or going more or less often than usual. The cause can be a urinary problem, kidney disease, pain, or stress, so a new change is a reason to see the vet rather than to scold.

"Cats are experts at hiding pain. So when they do give you a signal, it's worth taking seriously. It all comes back to knowing your cat's normal. Any change in eating, drinking, toileting, weight, or the way they move is worth a conversation with your vet."

Understanding Kidney Disease in Cats

Kidney disease is one of the most common conditions in older cats, affecting up to 40% of cats over ten, and nutrition is the single most powerful way to manage it.

A kidney disease diagnosis can feel scary and overwhelming, but it’s not the end of the road. Chronic kidney disease cannot be cured, but it can be managed well if caught early, and nutrition sits at the centre of that. A therapeutic renal diet has been shown to help cats with chronic kidney disease live longer. These diets control phosphorus and protein, add omega-3 fats, and support hydration, which together ease the load on the kidneys and protect quality of life.

Because the diet does so much of the work, helping a cat accept it and stay on it matters as much as the prescription itself. A renal diet works best when it is started early, introduced gradually, and fed consistently. Your vet will guide the change and monitor how your cat responds. Our guide to managing kidney disease in cats goes deeper, and cat kidney and urinary health covers the wider picture.

A standard blood test often will not flag that kidney function until about 75% of kidney function is already gone, which is why routine bloodwork at senior checks matters so much.

The One Emergency Every Cat Owner Should Know

If your cat is straining to urinate and producing little or nothing, treat it as an emergency, this behaviour could indicate a life-threatening blockage.

This is the one I never want you to wait on. A cat that strains repeatedly but passes little or no urine has a true emergency, most often a male cat with a urethral blockage. It needs a vet now — not tomorrow. Other signs are crying in the tray, restlessness, and vomiting. If you see this, visit your vet or an emergency clinic immediately. Our guide to urinary support in cats covers prevention once the crisis is past.

Why Twice-Yearly Vet Checks Matter

Because the signs stay quiet, two vet checks a year catch problems earlier than one.

A senior cat can be unwell long before it shows, so twice-yearly checks for senior pets give your vet the chance to find changes before they become a crisis. A check every six months is the rhythm most senior cats need.

At a senior check your vet weighs and scores your cat’s body condition, feels the thyroid gland and abdomen, checks teeth and joints, and often runs blood and urine tests to read the kidneys. Many conditions common in older cats, from kidney disease to an overactive thyroid, can be picked up this way before they show at home.

Nutrition for Senior Cats

A complete senior diet supports the whole aging cat at once: weight, muscle, joints, hydration, and the kidneys.

By the time most pet parents notice a senior cat is struggling, it has often been building for months, so feeding for the whole picture before symptoms show matters. Ageing cats frequently suffer from multiple conditions at the same time, and kidney disease and joint disease often occur together in cats.

Up to 90% of cats over the age of 12 show radiographic signs of joint deterioration. In one study of cats with degenerative joint disease, 68% also experienced chronic kidney disease.

A good senior diet works on several fronts:

Moisture, through wet food or added water, to keep an older cat hydrated and ease the workload on the kidneys.
Quality protein with controlled phosphorus, to preserve muscle while protecting kidney health.
Omega-3 fats for aging joints, skin, and coat.
Controlled calories to hold a healthy weight, since extra weight strains stiff joints.

Feeding your cat a complete and balanced diet, tailored to their ageing health needs is essential, and your vet can help you match your cat’s needs to a recommended diet.

Adjusting Your Home for an Ageing Cat

Small changes to a senior cat's environment keep them comfortable, mobile, and using their litter tray.

As cats age and their joints stiffen, a home they once navigated easily can become an obstacle course. A few adjustments help, and several of them double as ways to head off the toileting troubles above. These are the changes I suggest to support an older cat.

Switch to a low-sided litter tray. A stiff, arthritic cat can struggle to climb into a high-sided tray. A large, low-sided tray that is easy to step into often solves that on its own.
Add steps or ramps. If your cat loves a windowsill, the couch, or a favourite perch, steps or a ramp let them reach it without a painful jump.
Warm, supportive beds in their favourite spots. Soft bedding or a pet-safe heat mat in the sunny places they already love keeps aging joints comfortable. Keep food, water, litter, and a cosy bed within easy reach.
Keep the familiar familiar. Senior cats take comfort in routine, so try not to move their beds, bowls, or trays around.
Help with grooming. Older cats groom themselves less, so a gentle going-over with a soft brush keeps their coat healthy and doubles as a moment of affection.

Senior Cat FAQs

Why is my cat suddenly peeing outside the litter box?

A sudden change in toileting in an older cat usually means something is wrong, physical or emotional, rather than bad behaviour. Common reasons include urinary problems, kidney disease, pain, and stress. Because it is new, the first step is a vet check rather than a behaviour fix, especially if anything else has changed.

At what age is a cat a senior?

Cats are generally considered senior from around seven, and geriatric from about eleven. From the senior years, age-related changes such as kidney disease become more common, which is why twice-yearly checks are recommended from this age.

Why is my senior cat losing weight?

Gradual weight loss in a senior cat is one of the most common early signs of illness, so it is worth a vet check even if your cat seems well. Kidney disease, an overactive thyroid, diabetes, and dental pain are frequent culprits in older cats. A simple blood and urine test usually points to the cause, and the earlier it is found, the more your vet can do.

Why is my senior cat meowing more at night?

More night-time meowing in a senior cat often signals something has changed, rather than simple attention-seeking. Common reasons include an overactive thyroid, high blood pressure, fading sight or hearing, and the feline version of dementia. Because several of these are treatable, new or increasing night vocalising is worth raising with your vet.

Why is my senior cat sleeping more than usual?

Some extra sleep is a normal part of aging for cats, but a sudden or marked increase can point to a health problem. Pain from arthritis, kidney disease, or a thyroid issue can all leave an older cat more withdrawn and sleepy. If the change is recent, or comes with eating, drinking, or weight changes, book a vet check.

Helping Your Senior Cat Thrive

A senior cat can do really well with a little extra attention, and you are the one who makes it possible. Learn their normal, book a check every six months, and feed for their whole health picture, with a vet-directed renal diet if kidney disease is ever diagnosed.
