Older cats are not just slower versions of younger ones

As cats move into their double figures, their bodies change in ways that are easy to miss. Vets generally treat a cat as mature from around eight years old and senior from eleven, and from that point the purpose of a check-up shifts. Instead of waiting for symptoms and treating them, the aim becomes finding problems quietly, while they are still small, cheap to monitor and straightforward to manage.

Cats age gradually and compensate extraordinarily well. A cat whose kidneys are working at half capacity may look completely normal at home for months. By the time you notice something is wrong, a condition has often been developing for a long time. Regular appointments give your vet a series of measurements to compare, and trends tell a far richer story than any single result.

Cats hide illness by instinct

A cat that feels vulnerable will not announce it. It will sleep a little more, eat a little less, and stay closer to home — all of which look very much like "just getting older". Watch for these quiet signals, and mention any of them at your next visit:

• Drinking more and producing noticeably larger volumes of urine
• Weight loss despite a healthy or even increased appetite
• Hesitating before jumping onto a sofa or windowsill, or using the stairs differently
• Bad breath, drooling, eating on one side of the mouth, or dropping food
• Coat looking dull or greasy, or overgrooming one particular area
• Grumpiness when picked up, or hiding more than usual
• Vocalising at night, pacing, or seeming confused in familiar places

None of these are an inevitable part of ageing, and all of them are worth investigating.

What actually happens at a senior check-up

A thorough appointment is much more than a quick listen to the heart. Your vet will ask about appetite, water intake, litter tray habits, mobility and behaviour, then work through a full physical examination. Expect weight and body condition scoring, which is why the comparison with previous visits matters so much; feeling the thyroid glands in the neck; listening to heart and lungs; checking the mouth, eyes, ears, nails and skin; running hands over the body for lumps; and gently assessing joints through their range of movement.

Blood pressure is often included, because cats rarely show obvious signs of hypertension until it has damaged the eyes, kidneys, heart or brain. Blood tests and a urine sample are commonly recommended too. These can reveal kidney function, thyroid levels, blood sugar, anaemia and infection long before your cat seems unwell. A urine sample is especially useful, so ask in advance whether you should collect one at home.

Conditions that are far easier to manage when caught early

Early detection genuinely changes outcomes in older cats. The most common findings include:

• Chronic kidney disease — very common in senior cats. Early diagnosis allows dietary changes, better hydration, phosphate and blood pressure management, and regular monitoring that can add years of good quality life.
• Hyperthyroidism — often presents as weight loss with a ravenous appetite, restlessness or night vocalising. There are several effective treatment options.
• Osteoarthritis — affects a large proportion of older cats, even those who never limp. Pain relief, joint support, ramps, soft bedding and low-sided litter trays make a real difference.
• Diabetes — some cats achieve remission with prompt insulin treatment and diet changes.
• Dental disease — painful, frequently hidden, and linked to problems elsewhere in the body.
• High blood pressure — often secondary to kidney disease or hyperthyroidism, and a common cause of sudden blindness. Treatment is usually simple and inexpensive.

How often should an older cat see the vet?

As a general guide, healthy mature cats benefit from an annual health check, and senior cats from around eleven usually need one every six months, since six months in a cat's life is roughly equivalent to two to three years in ours. If your cat already has a diagnosis such as kidney disease or hyperthyroidism, your vet may suggest monitoring every three or four months.

Visits do not have to be stressful. Leave the carrier out for a week or two beforehand with a familiar blanket inside, and let your cat investigate it on its own terms. A towel over the carrier can reduce visual stress, and a pheromone spray may help. Top-opening carriers make examination far easier. Book a quiet mid-morning slot rather than a busy evening, and ask about calming support if your cat finds travel genuinely upsetting — some practices also offer home visits for very anxious patients.

Making the most of the appointment

A little preparation makes the twenty minutes far more valuable. Keep a simple note of your cat's weight if you can weigh them at home, along with appetite, drinking, litter tray habits and any changes in behaviour or mobility. Write your questions down in advance, because they are easy to forget in the consulting room.

Ask for the actual numbers and how they compare with previous results. Knowing that a kidney value has crept up steadily across three visits matters much more than a single reading in the normal range. Ask what to watch for before the next appointment, and what would warrant a phone call in between. If cost is a concern, say so early — many practices offer senior health plans or staged testing, and discussing it upfront is far better than skipping tests altogether.

The goal is not to find something wrong at every visit. It is to build a clear picture of what is normal for your cat, so that any change is noticed quickly. For an older cat, a regular check-up is one of the kindest and most practical things you can provide.
