Senior Cat Care: What Age Is a Cat Senior, and Which Changes Aren't Normal
Cats are senior at 10+ (AAHA/AAFP). Learn normal vs. worrying signs of aging, how often to see the vet, senior bloodwork costs, and arthritis and dementia tips.

The short answer: Under the 2021 AAHA/AAFP Feline Life Stage Guidelines, cats are "mature adults" from 7 to 10 years and "seniors" from 10 years on. Some slowing down is normal at that age. Weight loss, drinking more, a change in litter box habits, and new nighttime yowling are not normal. These are signs to get checked, and many of their causes, including kidney disease, an overactive thyroid, diabetes, and arthritis, can be managed if they are found early. For most senior cats, that means a vet checkup every six months, with bloodwork.
This is general information, not veterinary advice. If your cat seems unwell, contact your vet or an emergency clinic.
What age is a cat considered senior?
The answer depends on which source you ask. They do not really disagree.
- AAHA/AAFP 2021 Feline Life Stage Guidelines: mature adult 7–10 years, senior 10 years and older, plus a separate end-of-life stage that can happen at any age. These are the guidelines most US vets use.
- AAFP's owner site, catfriendly.com: describes cats as senior at 11 years, which it says is roughly 60 in human years.
- Cats Protection (UK): calls cats elderly or senior at 11 and "super senior" or geriatric at 15.
In practice, plan for senior care from around your cat's 10th birthday. From about age 7, start watching more closely for changes. Many age-related diseases begin quietly in the mature-adult years. Cornell's Feline Health Center notes that the behavioral signs of cognitive dysfunction usually become clearly noticeable from age 10.
Normal aging vs. signs that need a vet
Every cat ages differently. Use this table as a starting point, not a diagnosis. If you are unsure, assume it is "not normal" until your vet says otherwise. Cats are very good at hiding illness (see our guide to signs a cat is hiding being sick).
| What you notice | Often normal with age | Not normal: book a vet visit | Possible causes your vet will consider |
|---|---|---|---|
| Sleep | Sleeping a little more, seeking warm spots | Restless at night, wandering, yowling, or sleeping much more than usual all at once | Pain, hyperthyroidism, high blood pressure, cognitive dysfunction |
| Weight | Stable weight; slight loss of muscle tone | Any steady loss between weigh-ins, or a bony spine and hips | Kidney disease, hyperthyroidism, diabetes, dental disease, cancer |
| Appetite | Slightly pickier, prefers softer food | Eating much more yet losing weight, or not eating for 24 hours or more | Hyperthyroidism, diabetes, dental pain, nausea |
| Thirst and urine | No obvious change | Drinking more, larger or more frequent clumps, an empty water bowl | Kidney disease, diabetes, hyperthyroidism |
| Litter box | Same habits | Going just outside the box, straining, or new urine marking | Arthritis, increased urine output, urinary disease, hyperthyroidism |
| Jumping and movement | A bit slower to get going | Stops jumping onto favorite perches, hesitates on stairs, walks stiffly | Degenerative joint disease (arthritis) |
| Grooming and coat | Coat slightly duller | Matting along the back and hips, greasy or unkempt coat, overgrown claws | Arthritis pain, dental disease, illness |
| Behavior | Calmer, likes routine | New irritability, hiding, or aggression when handled | Pain (often dental or joint), cognitive dysfunction |
Cornell's Feline Health Center notes that the extra urine produced by kidney failure, diabetes, or hyperthyroidism can make a litter box get dirty faster. Arthritis can make getting into the box hard, especially if your cat has to use stairs to reach it. A "behavior problem" in an older cat is often a medical problem.
The big four: kidneys, thyroid, diabetes, and blood pressure
The most common reasons older cats lose weight or start drinking more are:
- Chronic kidney disease (CKD). Cornell describes kidney failure as a common disease in older cats with "extremely varied" symptoms. Look for thirst, more urine, weight loss, a poor appetite, and sometimes vomiting.
- Hyperthyroidism. An overactive thyroid often makes cats hungry, restless, and vocal while they lose weight. It can also cause high blood pressure.
- Diabetes mellitus. Overweight cats are at higher risk. It shows up as thirst, more urine, and weight loss despite a good appetite.
- Hypertension (high blood pressure). This is usually caused by kidney disease or hyperthyroidism. According to Cornell, it can damage the retina and cause sudden blindness, which often looks like confusion or nighttime crying.
None of these can be confirmed by how your cat looks. All of them can be detected with blood tests, a urine test, and a blood pressure reading. That is why senior checkups matter.
Senior checkups: how often, what's included, and what it costs
The AAFP's catfriendly.com recommends that cats aged 10–15 see the vet at least every 6 months, and cats over 15 every 4 months. Cats age faster than we do, so six months in a cat's life is a long time for a problem to go unnoticed.
What a typical senior visit includes
- A full physical exam, including the teeth, joints, thyroid area, heart, and eyes
- Weight and body condition score, compared with the last visit
- Bloodwork: a complete blood count, chemistry panel (kidneys, liver, glucose), and usually a thyroid level (T4)
- Urinalysis, which shows how well the kidneys concentrate urine and checks for sugar or infection
- A blood pressure measurement
Typical costs (USD and GBP)
Prices vary a lot by region and clinic. Use these figures to plan your budget, not as a quote.
| Item | US (source: CareCredit national averages) | UK (source: ManyPets vet survey) |
|---|---|---|
| Routine exam or consultation | $57–$130 for cats | £44–£81 (UK average about £62) |
| Blood tests | About $125 (thyroid) to $144 (chemistry panel) per test | From around £100 for in-house testing; more if sent to an external lab |
| Urinalysis | About $54 | Ask your practice; often bundled with blood tests |
| Blood pressure check | About $35 | Ask your practice |
Together, a full senior workup usually costs a few hundred dollars or pounds. Many clinics offer a cheaper "senior wellness" package or a monthly health plan. Ask whether one is available, and check what your pet insurance covers. Most policies exclude routine screening. If you are choosing a new clinic for an older cat, our guide on questions to ask a vet can help you compare options.
Arthritis: the most under-recognized senior change
Cornell and the AAFP both describe degenerative joint disease (arthritis) as common in older cats. Cats rarely limp, so it is easy to miss. Watch for:
- Stopping jumping, or using a chair as a "step" to reach a counter or bed
- Hesitating at the top or bottom of the stairs
- Peeing or pooping just outside the litter box
- Matting over the lower back and hips, where twisting to groom now hurts
- Overgrown claws from scratching less, and grumpiness when stroked along the spine
Home changes that help right away
- Litter boxes: use at least one box with a low entry of about 2–3 in (5–8 cm) on every floor your cat uses. Our article on common litter box mistakes covers placement and cleaning.
- Steps and ramps up to the sofa, bed, and favorite windowsill, so your cat keeps the high spots it values.
- Warm, padded beds in draft-free spots on the floor, not only high up.
- Rugs or runners on slippery floors.
- Gentle daily play at floor level to keep muscles working. Our ideas for indoor cat exercise work well when scaled down for older cats.
- Grooming help: short, gentle brushing sessions for areas your cat can no longer reach. See grooming without daily battles.
Never give human pain relievers. Acetaminophen (paracetamol) and ibuprofen are toxic to cats. Your vet can prescribe cat-safe pain relief.
Cognitive dysfunction: "kitty dementia"
Cornell's Feline Health Center describes cognitive dysfunction as a progressive condition similar to Alzheimer's disease in people. Its signs become clearly noticeable from about 10 years of age. They include:
- Disorientation, such as getting "stuck" in corners or staring at walls
- Loud vocalizing, especially at night
- Changes in sleep and wake cycles
- Forgetting where the litter box is
- Changes in social behavior, such as becoming clingy or withdrawn
Many of these signs overlap with hyperthyroidism, high blood pressure, kidney disease, and arthritis, so your vet will rule those out first. After that, management usually focuses on a predictable routine, easy access to food, water, and litter boxes, gentle enrichment, and sometimes medication or an adjusted diet prescribed by your vet. Cornell also advises against bringing a stressful new animal into the home of a cat with cognitive decline.
Feeding and hydration for older cats
- Weigh monthly. catfriendly.com notes that slow weight change is hard to see and suggests weighing at home with a baby scale. Write the number down, because the trend matters more than any single reading.
- Appetite: Cornell says a weaker sense of smell can reduce interest in food. Gently warmed wet food often helps. If your cat skips meals, read our guide to a cat that has stopped eating. Cats should not go without food for long.
- Hydration: provide several water stations and wide, shallow bowls. Wet food adds moisture. Our guide on choosing an affordable wet cat food explains what to look for on the label.
- Don't switch to a "senior" diet on your own if your cat has kidney disease or another diagnosis. Your vet may recommend a specific therapeutic diet instead.
- In multi-cat homes, make sure an older or slower cat gets to eat in peace. See feeding multiple cats without food wars.
A simple monthly senior checklist
- Weigh your cat and record the result.
- Run your hands along the spine and hips to check for muscle loss and matting.
- Notice whether the water bowl empties faster than it used to.
- Count litter clumps: are they bigger or more frequent?
- Check whether your cat still uses its usual high perches.
- Note any night vocalizing, confusion, or new hiding.
- Look at the teeth and gums, and sniff for bad breath.
Take these notes to every checkup. Short, dated observations help your vet spot trends more than anything else you can bring.
Frequently asked questions
At what age is a cat a senior?
The 2021 AAHA/AAFP Feline Life Stage Guidelines define senior cats as 10 years and older, with a "mature adult" stage from 7 to 10. catfriendly.com and Cats Protection use 11 years. Either way, plan for senior care around age 10.
Is it normal for an older cat to lose weight?
No. Older cats may lose some muscle tone, but steady weight loss is a common early sign of kidney disease, hyperthyroidism, diabetes, dental disease, or cancer. Book a vet visit and ask about bloodwork.
How often should a senior cat see the vet?
catfriendly.com recommends at least every 6 months for cats aged 10–15, and every 4 months for cats over 15. Go sooner if you notice any of the "not normal" signs above.
Why is my old cat yowling at night?
Common causes include hyperthyroidism, high blood pressure (which can affect vision), pain, hearing or vision loss, and cognitive dysfunction. Your vet should rule out medical causes before it is put down to "just old age."
