Senior Cats

Cats are living longer than ever — and many go on to enjoy happy, comfortable lives well into their teens and beyond. But getting older does bring changes, and the more you understand what to expect, the better placed you'll be to spot when something needs attention. One of the most important things to know about senior cats is that changes in behaviour or health are rarely "just old age" — most have a cause, and many are very treatable. Don't write things off. Your vet is your most important partner in keeping your older cat thriving.

When Is a Cat Considered Senior?

Cats are generally considered senior from around ten years old, and super-senior or geriatric from fifteen onwards. In human terms, a ten-year-old cat is roughly equivalent to a person in their mid-fifties — and just as with people, the ageing process varies enormously between individuals. Some cats show very few signs of slowing down until quite late in life; others begin to need extra support earlier.

From around seven years old, changes begin to happen at a cellular level — metabolism slows, the immune system becomes a little less robust, and organs gradually become less efficient. You won't necessarily see outward signs of this for several more years, but it's one of the reasons why regular vet checks become increasingly valuable from middle age onwards.

Changes You Might Notice

Ageing brings gradual shifts that can be easy to miss or put down to your cat simply "getting older." Some are a normal part of the process — others are worth investigating. Signs to be aware of include:

Sleeping more than usual, or seeming less engaged with everyday life
Moving more slowly, being reluctant to jump, or stiffness after resting
Changes in appetite — eating more or less than usual
Increased thirst and more frequent trips to the litter tray
Weight loss, even if appetite seems normal or increased
Changes in coat condition — looking duller, feeling coarser, or becoming unkempt
Confusion, disorientation, or changes in behaviour
Increased or unusual vocalisation, particularly at night
Changes in litter box habits
Apparent changes in vision or hearing

Many of these overlap with specific health conditions — which is exactly why they're worth mentioning to your vet rather than assuming they're simply age-related. Cats are very good at masking discomfort, so changes in behaviour are often the first and sometimes the only clue that something needs attention.

The Most Common Conditions in Senior Cats

Chronic Kidney Disease (CKD) is one of the most frequently diagnosed conditions in older cats, and often develops slowly over many years. Early signs include drinking more water than usual, urinating more frequently, and gradual weight loss. As the condition progresses, cats may become nauseous, lose their appetite, and become lethargic. CKD can't be cured, but with the right management — including dietary changes and sometimes medication or fluid therapy — many cats live comfortably for years after diagnosis. Early detection through routine blood and urine tests makes a real difference to outcomes.

Hyperthyroidism is another extremely common condition in older cats, caused by the thyroid gland producing too much hormone. It speeds everything up — affected cats often eat more but lose weight, become restless or irritable, drink and urinate more, and may have a poor coat or vomit frequently. Despite how unsettled they appear, hyperthyroidism is very manageable. Treatment options include daily medication, a specialised diet, or a one-off radioactive iodine treatment, and most cats do very well once treated.

Arthritis is far more common in cats than many owners realise — and because cats tend not to limp in the obvious way dogs might, it often goes undetected. Instead, arthritic cats gradually do less: they stop jumping to favourite spots, become slower on stairs, groom less thoroughly, or are reluctant to be touched in certain areas. Pain management, joint supplements, and small adjustments around the home can make an enormous difference to a cat's daily comfort and quality of life.

Diabetes occurs when the body can no longer regulate blood sugar properly. Signs include increased thirst and urination, weight loss, a dull coat, and in more advanced cases, a distinctive weakness in the hind legs. Diabetes requires lifelong management, but with consistent care — usually insulin injections and a controlled diet — many diabetic cats live well.

High Blood Pressure (Hypertension) is common in senior cats and often develops as a consequence of kidney disease or hyperthyroidism. It can cause damage to the eyes, kidneys, heart, and brain — and is one of the most common causes of sudden blindness in older cats. It's detected with a simple blood pressure check and managed with medication.

Cognitive Dysfunction — Feline Dementia

Cats can develop a condition very similar to dementia in humans, known as Cognitive Dysfunction Syndrome (CDS). It's thought to affect a significant proportion of cats over fifteen, though it often goes unrecognised.

Signs can include disorientation — getting stuck in corners, seeming confused in familiar surroundings, or appearing to forget routines they've followed for years. Affected cats may become more vocal, particularly at night, become more clingy or conversely more withdrawn, stop using the litter tray reliably, or lose interest in food and interaction.

It's worth knowing that many of these signs can also be caused by other conditions — hyperthyroidism, high blood pressure, kidney disease, and pain from arthritis can all look similar. Your vet will want to rule these out before concluding that CDS is the cause, as many of the mimicking conditions are very treatable. CDS itself can't be cured, but its progression can often be slowed with the right environment, diet, and in some cases medication. Keeping your cat's world consistent and stimulating, without overwhelming them, is one of the most helpful things you can do.

Making Home Life Easier

Small adjustments around your home can make a big difference to an older cat's daily comfort and confidence.

Provide soft, warm bedding in several locations — older cats feel the cold more and may not always be able to reach their favourite spot
Consider a heated cat bed or a self-warming mat
Make sure food, water, and litter trays are easily accessible without needing to climb or jump — having everything on one level is ideal
Use a litter tray with a lower entrance if your cat is stiff or has joint pain
Keep litter trays scrupulously clean — senior cats can become more particular, and a soiled tray may put them off using it
Avoid rearranging furniture — older cats, particularly those with any degree of cognitive decline or vision changes, find consistency reassuring
Provide ramps or steps to help your cat reach favourite resting spots without jumping
Trim claws more regularly — older cats tend to be less active and their claws may become overgrown and uncomfortable

Vet Checks — Why Twice a Year Matters

Once your cat reaches senior years, twice-yearly vet checks are strongly recommended rather than the annual visit that may have been sufficient when they were younger. A lot can change in six months for an older cat, and many of the conditions most common in senior cats — kidney disease, hyperthyroidism, hypertension — can be caught much earlier through routine blood and urine testing than by waiting for visible symptoms to appear.

Early detection isn't just better for your cat's health and comfort — it's usually better for the budget too. Conditions caught early are generally less complex and less costly to manage than those that have progressed significantly before diagnosis.

If your cat hasn't had a health check in the last six months and is over ten years old, it's worth booking one. And if anything at home feels different — even if you can't quite put your finger on what — mention it to your vet. You know your cat better than anyone.
