Senior Cat Health Checklist

Cats are considered mature from seven and senior from eleven, and the single most valuable thing you can do from around seven is start annual bloodwork — because almost every serious condition older cats develop is easier to manage when caught before the signs appear. The second most valuable thing costs nothing: weigh your cat monthly and write it down. Weight change is the earliest warning you'll get for kidney disease, hyperthyroidism, diabetes and cancer, and it's invisible by eye. This page is a practical checklist of what to watch at home, what your vet should check, and when. The cat cost calculator helps you budget for the senior years, which do cost more.

When Is a Cat Considered Senior?

Earlier than most owners expect, and the widely used life-stage framework splits it in two.

Seven feels young to be calling a cat "mature", and that's exactly why it's worth knowing. A seven-year-old cat looks and behaves like a young cat — which is precisely what makes it the ideal moment to establish baseline bloodwork. A normal result at seven is genuinely useful, because it gives your vet something to compare against when something changes at eleven.

There's a shift in what you're watching for, too. Through the mature years the risk is creeping weight gain. From around eleven, it flips — and unexplained weight loss becomes the finding that matters most.

What Should You Check at Home?

Five things. None takes more than a minute.

Monthly: weigh your cat. Bathroom scales work — weigh yourself, then yourself holding the cat, and subtract. Write down the date and weight in a note on your phone. This is the single highest-value habit on this page, because a cat losing half a pound over four months looks identical each morning and is telling you something important.

Monthly: lift the lip. Thirty seconds. Look for a red band along the gum line, yellow-brown tartar, or receding gums. Smell the breath — a strong odor isn't "just cat breath". Details are in dental disease in cats.

Weekly: look at the litter tray. You're watching clump size and number. Bigger or more frequent clumps mean more urine, which is one of the earliest signals of kidney disease or diabetes. In a single-cat home this is one of the best warning systems you have.

Ongoing: notice what your cat has stopped doing. Has she stopped getting onto the windowsill? Does he take the stairs one at a time? Abandoned high places are usually arthritis, as covered in arthritis in cats — and it's treatable.

Ongoing: run your hands over your cat. During normal stroking, feel along the spine, hips and shoulder blades for bones becoming more prominent, and check for lumps, matted patches or sore spots. A coat that's suddenly unkempt over the back half often means your cat can't twist comfortably to groom.

What Should Your Vet Check?

More than a physical examination, and this is where the real value sits.

From age seven, annually:

• Full physical exam — heart, lungs, abdomen, joints, mouth, eyes
• Weight and body condition, compared against previous visits
• Blood panel covering kidney values (including SDMA, which rises earlier than creatinine), liver, blood sugar and thyroid hormone
• Urine test, which reveals things blood alone can't — particularly how well the kidneys are concentrating urine
• Blood pressure, since high blood pressure is common in older cats and can quietly damage eyes, kidneys, heart and brain

From around eleven, twice yearly. Cats age faster than we do, so twelve months is a long gap. Six-monthly visits catch changes while they're still small, and visit frequency is covered in how often should a cat go to the vet.

Also worth discussing: dental assessment and whether a scale and polish is due, parasite prevention appropriate to your cat's lifestyle, whether vaccination still suits an indoor senior, and pain — specifically, ask about arthritis rather than waiting to be asked.

One tip that genuinely improves appointments: bring your weight log. "She's dropped from 4.6 to 4.2 kg since March" gives your vet somewhere concrete to start, and it's far more useful than "she seems about the same".

What Conditions Should You Watch For?

Five account for most of what vets see in older cats, and they share overlapping early signs — which is why bloodwork rather than guesswork settles things.

Notice how much overlap there is. Increased thirst appears in three of them. Weight loss appears in four. That's the whole argument for testing rather than assuming: you genuinely cannot tell these apart at home, and they need completely different treatment.

The encouraging part is that all five respond well to early intervention. Hyperthyroidism can often be cured outright. Diabetes can go into remission. Kidney disease can be slowed for years. Dental disease is preventable and treatable. Arthritis is very manageable. Each has a full guide: kidney disease, hyperthyroidism, dental disease and arthritis.

What Changes at Home for a Senior Cat?

Small adjustments, disproportionate benefit.

Litter trays. Switch to low-sided, open trays — the single most impactful change for an older cat. High walls and covered entrances are genuinely hard work for stiff joints, and "accidents" often stop the day access gets easier. Put a tray on every floor.

Access. A step or low stool by the sofa, the bed and a favorite windowsill. Cats that had given up on your bed frequently start sleeping there again.

Warmth and comfort. Older cats feel the cold more and stiff joints appreciate warmth. A padded bed, low to the ground, somewhere draught-free.

Food and water. Raise bowls slightly so your cat isn't crouching low to eat. Add water bowls in more rooms — hydration matters more with age, especially with kidney disease in the picture. Many senior cats do better on wet food.

Grooming help. Brush the areas your cat can no longer reach — lower back, hips, tail base — gently, since those spots may be sore. Keep claws trimmed, since less scratching means less natural wear.

Non-slip surfaces. Rugs or mats on hard floors give an unsteady cat confidence.

Keep playing. Shorter, gentler sessions, but keep them going. Movement maintains muscle and mental sharpness. Broader guidance is in how to care for a senior cat.

When Should You Call the Vet Straight Away?

Most senior changes can wait for a routine appointment. These shouldn't.

Same day:

• Straining in the litter tray with little or nothing produced — possible urinary blockage, a genuine emergency, especially in male cats
• Not eating for more than 24 hours — cats are prone to a serious liver condition when they stop eating
• Difficulty breathing, open-mouth breathing or panting
• Collapse, sudden weakness, or dragging a limb
• Sudden blindness or bumping into things — can indicate dangerously high blood pressure
• Repeated vomiting, or vomiting with lethargy

Within a few days:

• Unexplained weight loss
• A clear increase in thirst or urination
• A new lump, or one that's changing
• Persistent bad breath or drooling
• A marked change in appetite, in either direction
• Hiding, or a sudden change in temperament

That last one deserves emphasis. In an older cat, a personality change is frequently a physical problem. A previously affectionate cat that has become withdrawn or snappy is often in pain rather than in a mood — and it's usually fixable.

What About a Senior Cat's Diet?

Less settled than most owners assume, and worth a conversation rather than a default.

The instinct is to switch to "senior" food at seven, but there's no single agreed formulation for senior cats, and the label means different things across brands. Some senior diets are lower in calories for less active cats; others are higher in calories and protein for older cats losing condition. Those are opposite products aimed at opposite problems.

What actually matters:

Protein. Older cats generally need more protein, not less, because they become less efficient at using it and lose muscle with age. The old advice to restrict protein in seniors has largely been revised — unless your cat has a specific diagnosis that calls for it.

Calories change direction. Through the mature years many cats need fewer calories as activity drops. Past twelve, many need more, because digestion becomes less efficient. This is why a senior losing weight shouldn't simply be left on the same food.

Moisture matters more. Kidney function declines with age, and wet food helps. If your cat has always eaten dry, adding a wet meal is a small change with real benefit.

Therapeutic diets are different. A prescription kidney, urinary or diabetic diet is a treatment, chosen for a diagnosis. Those aren't interchangeable with over-the-counter senior food, and switching between them is a vet decision.

Palatability becomes a genuine issue. Sense of smell fades with age, and dental discomfort makes eating harder. Warming food slightly lifts the aroma and often tempts a reluctant senior to start.

The practical answer: ask your vet what suits your individual cat at the annual check, rather than switching on a birthday. And never restrict a senior cat's food to manage weight without veterinary input — cats are prone to serious liver problems when intake drops sharply.

What Does Senior Cat Care Cost?

More than the middle years, and worth planning for rather than being surprised by.

Realistically, $700 to $1,200 a year for a healthy senior with no diagnoses, rising to $2,000–$4,000 once a chronic condition is being managed.

Two honest notes. Insurance only helps if it predates any signs — once a condition appears it's excluded from new policies universally, which is why the decision to insure belongs in the young adult years rather than at eleven. And the monitoring costs are the ones that save money, because a condition caught early is nearly always cheaper to manage than one caught late.

Frequently Asked Questions

At what age is a cat considered senior?

Cats are generally classed as mature adults from seven and senior from eleven, with geriatric from fifteen. Seven is the point to start annual bloodwork, even though a seven-year-old cat usually looks and behaves like a young one.

What should be included in a senior cat checkup?

A full physical exam, weight and body condition compared to previous visits, a blood panel covering kidney, liver, thyroid and blood sugar, a urine test, and a blood pressure check. Dental assessment and a conversation about mobility should also be part of it.

How often should a senior cat see the vet?

Annually from seven, and twice yearly from around eleven. Cats age faster than people, so twelve months is a long gap in later life — six-monthly visits catch changes while they're still small and cheap to address.

Why does my senior cat keep losing weight?

Unexplained weight loss in an older cat is a symptom rather than a success, and it's one of the most useful early signals you'll get. Common causes include hyperthyroidism, kidney disease, diabetes and dental pain — all treatable, and all needing bloodwork to tell apart.

What are the most common health problems in older cats?

Chronic kidney disease, hyperthyroidism, diabetes, dental disease and arthritis. They share overlapping early signs such as thirst and weight loss, which is why blood and urine testing rather than guesswork is how they're distinguished.

How can I make my home easier for an older cat?

Switch to low-sided open litter trays, add steps to favorite high spots, provide a warm bed low to the ground, raise food and water bowls slightly, put rugs on slippery floors, and help with grooming the areas your cat can no longer reach.

The senior years are far more manageable than they sound, and almost all of it comes down to noticing early. Two habits do most of the work: weigh your cat monthly and write it down, and get annual bloodwork from age seven. Between them they catch nearly every condition on this page before your cat looks unwell — which is exactly when there's most to gain. Everything else here is small comforts: a lower litter tray, a step by the sofa, a warm bed. Plan the costs with the cat cost calculator, and put a monthly weigh-in reminder on your phone today.
