Your Cat Is Getting Older: Recognising the Signs and Adjusting Their Care

How do you know your cat is becoming a senior? Physical signs, behaviour changes and practical tips for adjusting their care.

Around the age of eleven, most cats enter a new life stage: the senior years. It usually happens gradually and almost unnoticed — a jump onto the windowsill that's slightly more hesitant, a nap that lasts a little longer, or a food bowl that's left untouched more often. Short answer: a cat is generally considered a senior from around 11 years old, and geriatric from around 15. The main signs of ageing are stiffer joints, changes in weight, a duller coat, changes in drinking or toileting habits, and subtle shifts in behaviour. Below you'll find how to recognise these signs and which practical changes to diet, home and care make a real difference.

From what age is a cat a senior?

Vets usually divide a cat's life stages after adulthood into three steps: mature (roughly 7 to 10 years), senior (11 to 14 years), and geriatric (15 years and older). This is a guideline, not a fixed rule — an active, lean indoor cat can still seem surprisingly youthful at twelve, while an overweight cat or one with a chronic condition may already show clear senior traits at nine. Breed, lifestyle (indoor only or also outdoor) and health history all play a part. It's therefore smarter to watch for concrete signs rather than relying on age alone.

Physical signs that your cat is getting older

Ageing in cats tends to creep up gradually. Cats are also masters at hiding discomfort, so it pays to look a little more closely than usual.

Joints and movement

Osteoarthritis is very common in older cats but is often missed because cats rarely limp obviously. Watch for: jumping less, hesitating before a jump, avoiding stairs, stiffness after getting up, or suddenly avoiding a litter tray with a high rim.

Weight and muscle mass

Both unwanted weight gain (from reduced activity) and weight loss (for example from kidney problems or an overactive thyroid) can occur. Feel along the spine regularly: prominent vertebrae with little muscle around them is a sign of muscle loss, even if the weight itself seems stable.

Coat and skin

A duller, matted or greasy coat often develops because older cats are less flexible and can no longer groom themselves as thoroughly. Reduced skin elasticity and thicker claws that grow out faster are also part of ageing.

Teeth and eating

Gum disease and dental wear are very common in older cats. Signs include: slower or one-sided chewing, kibble left uneaten, drooling, or avoiding hard pieces while still eating wet food.

Senses: sight and hearing

Reduced vision (often most noticeable in the dark) and hearing loss usually develop slowly. A cat that meows louder than before, startles at touch, or seems more uncertain in a new environment may already be compensating for a fading sense.

Drinking and toileting more

A clear increase in drinking and urinating is a sign you shouldn't simply put down to old age — it's a classic sign of declining kidney function or an overactive thyroid, and it always deserves a vet check.

Behaviour changes in an older cat

Alongside physical signs, behaviour changes too. Many senior cats become calmer and sleep more, which is normal in itself. Do watch for: confusion or disoriented wandering, loud meowing at night, toileting outside the litter tray when that never used to happen, less interest in play or attention, or conversely becoming more affectionate than before. These shifts can point to pain, reduced sight or hearing, or in older cats also cognitive decline (similar to dementia). Any approach should always start with ruling out a medical cause, not blaming the cat's temperament.

Adjusting the diet for the senior years

Senior cat food usually contains fewer calories (to prevent weight gain in less active cats), adjusted protein and phosphorus levels to ease the workload on the kidneys, and often extra joint support. Always introduce a food change gradually over seven to ten days to avoid digestive upset. If stiffness persists, a supplement is never a substitute for a proper diagnosis from your vet.

Practical changes around the home

Small changes at home make a noticeable difference to an older cat's comfort. Choose a litter tray with a low entry point so stepping in is no longer a strain on stiff hips. Place food and water bowls in multiple, easily reachable spots on the ground floor, and use a raised bowl to avoid an uncomfortable neck position while eating. Provide soft, warm resting spots that don't require a high climb — a comfortable option is the Gor Pets Memory Foam Ultima Sleeper, and consider steps up to favourite spots such as the windowsill. Keep a closer eye on claws: less climbing and scratching means less natural wear, so claws may grow out or curl in faster.

When should you see the vet?

Contact your vet sooner than you might usually: a clear increase in drinking or urinating, unintentional weight loss, lameness lasting more than a few days, appetite changes lasting more than a few days, breathing difficulties, or sudden confusion. Many senior conditions — kidney problems, thyroid disease, osteoarthritis, dental disease — can be managed well if caught early. From around eleven years old, an annual (ideally six-monthly) health check with bloodwork is a sensible investment, even without visible symptoms.

Common mistakes in caring for an older cat

Three things owners often overlook: putting changes down to "just getting old" without consulting the vet, when pain and illness are often very treatable; switching to senior food too late, unnecessarily increasing weight gain or strain on the kidneys; and not adapting the home until the cat is already visibly struggling, rather than proactively getting a low-entry litter tray or an extra resting spot on the ground floor.

Frequently asked questions

Is my cat already a senior at ten?
Not necessarily — 10 years usually still falls within the "mature" stage. Look mainly at signs such as stiffness, weight changes or altered drinking habits rather than age alone.

Do I have to switch my cat to senior food from age 11?
Not automatically. A healthy, active cat with no symptoms can happily stay on regular adult food. If in doubt, check with your vet, especially if there are already weight or kidney concerns.

Why is my old cat suddenly meowing much more, especially at night?
This can point to reduced hearing or sight, pain, an overactive thyroid, high blood pressure, or cognitive decline. Always have your vet rule these out before putting it down to behaviour alone.

How often should an older cat see the vet?
From around 11 years old, a check-up every six to twelve months is recommended, even without visible symptoms, since many senior conditions are barely noticeable in their early stages.

In short

Cats age gradually, and the signs are often subtle: stiffer joints, changing weight, a less well-groomed coat, altered eating, drinking or toileting habits, and shifts in behaviour. By watching for these early, adjusting diet and home environment, and scheduling regular health checks, you can keep your cat's senior years as comfortable as possible. Unsure about a particular sign? Always contact your vet — they're best placed to judge whether something is simply part of ageing or needs treatment.
