Is Your Cat Slowing Down? Signs of Aging & the Supplements That Actually Help
Cats are experts at hiding pain. Most of the real signs of aging look like "she's just getting lazy" — until you know what to actually look for.

Quick answer: Watch for hesitation jumping onto furniture, less grooming, sleeping more, litter box misses, and changes in appetite or thirst — these are the signs cats actually show as they age, and they're easy to write off as "just getting older." Cats are now considered senior around 12-14 (not the old 8-year marker), and joint discomfort is far more common than most owners realize. A vet visit, not a supplement alone, is the right first step if you notice any of these.
Key takeaways
✓Over 90% of cats show radiographic evidence of degenerative joint disease as they age — most owners never know because cats mask pain so well.
✓The real signs are behavioral: hesitating to jump, less grooming, more sleeping, litter box misses — not limping.
✓Geriatric cats benefit from six-month vet checkups; healthy seniors from a yearly geriatric exam plus a smaller mid-year visit.
✓Joint and mobility supplements can support comfort, but they're not a substitute for a veterinary diagnosis.
A cat who sleeps eighteen hours a day at three doesn't look much different from one who sleeps eighteen hours a day at thirteen. That's exactly the problem — the signs of feline aging are subtle by nature, and cats are instinctively good at concealing pain and stiffness, a survival trait left over from being both predator and prey. Most owners don't miss the signs because they aren't paying attention; they miss them because the signs look like normal cat behavior. Here's what's actually worth watching for, what the numbers say about how common this is, and what genuinely helps versus what's just marketing.
When Is a Cat Actually "Senior"?
The old rule of thumb — a cat is a senior at 8 — is outdated. Cornell's Feline Health Center now places cats in the "older" category at 12 to 14 years, reflecting how much better feline veterinary care and nutrition have gotten. That doesn't mean nothing changes before then — some cats show early signs of joint discomfort well before 12 — but it does mean an 8- or 9-year-old cat acting a little different isn't automatically "just getting old." It's still worth a vet visit to rule out something else first.
Signs Easy to Miss
Per NC State's Comparative Pain Research Center, cats with joint pain rarely limp the way dogs do. Instead, watch for:
🐾
Hesitating before jumping
Pausing before a jump they used to make without thinking, or taking a running start where they didn't need one before.
🛋️
Preferring lower surfaces
Giving up favorite high perches for the floor or a low bed, even when the high spot is still accessible.
🧼
Less grooming, especially the hindquarters
A duller or matted-looking coat, particularly toward the back half, since grooming there requires more flexibility.
😴
Sleeping more, playing less
A gradual drop in activity over weeks or months — easy to miss because it doesn't happen overnight.
🚽
Litter box misses
Discomfort getting in and out of a high-sided box, or squatting, can show up as accidents just outside it.
Cornell adds a few more general flags worth watching regardless of age: meowing more than usual, not responding when called, and any change in eating or sleeping patterns. Their guidance is blunt about it — any behavior or health change, sudden or gradual, is worth a vet visit rather than an assumption.
A vet visit — not a guess at home — is the right way to confirm what's actually going on.
The Arthritis Numbers Most Owners Don't Know
This is the statistic that surprises most cat owners: according to NC State's Comparative Pain Research Center, over 90% of cats show radiographic evidence of degenerative joint disease as they age. That's a strikingly high number for a condition most people associate with dogs. The mismatch between how common it is and how rarely it's caught comes down entirely to how well cats hide it — no limping, no yelping, just a slow drift toward doing less.

How Often Senior Cats Should See the Vet
1
Healthy seniors: once a year, plus a smaller mid-year check
Cornell recommends a yearly geriatric exam — including bloodwork and X-rays — plus a smaller checkup in between for cats who are otherwise doing well.
2
Geriatric or already-diagnosed cats: every six months
Cornell's guidance steps this up to six-month checkups once a cat is genuinely geriatric or managing an ongoing condition — changes can happen faster at this stage.
3
Any new sign, any time: don't wait for the scheduled visit
The
AAFP's senior care guidelines specifically cover pain management, nutrition and weight changes, and quality-of-life assessment in aging cats — exactly the kind of thing worth flagging between scheduled exams, not saving for the next one.
Supplements That Actually Help
Two categories are genuinely worth a look for a senior cat, alongside — never instead of — a vet's opinion: joint/mobility support (above) and general anti-inflammatory support. Neither replaces a diagnosis, and neither should be marketed as one; treat "supports mobility" and "supports comfort" as exactly what they say, not a cure.
General wellness
Rooted Owl® Turmeric Curcumin Wellness Support
$34.00 · 500 in stock
Curcumin with black pepper (for absorption) and Vitamin C, formulated for both dogs and cats. Positioned as everyday comfort and mobility support rather than a treatment — a reasonable daily-routine addition once a vet has ruled out anything that needs direct treatment.

If appetite is the issue, not joints
Not every "slowing down" sign is joint-related — a senior cat that's eating less can also lose muscle and energy fast. A more palatable, easy-to-digest food can help where a picky senior has started turning up their nose at kibble. Spoiled Pets' Chicken and Salmon Balanced Bowl ($12.00) is a freeze-dried raw, AAFCO all-life-stages formula that rehydrates with warm water or broth — worth trying as a topper if a senior cat's appetite has genuinely dropped, alongside a vet visit to rule out the more serious causes of appetite loss (dental pain, kidney disease) that a food swap alone won't fix.
Myths vs. Facts
MythCats show arthritis pain the same way dogs do — limping, favoring a leg.
FactCats mask pain through behavior changes — hesitating to jump, less grooming, sleeping more — rarely a visible limp.
MythA cat isn't a "senior" until 8, so nothing needs checking before then.
FactCornell now places "older" at 12-14, but any behavior change at any age is worth a vet visit, not an age cutoff.
MythA joint supplement is basically the same as treatment for arthritis.
FactSupplements can support comfort and mobility, but a veterinary diagnosis and treatment plan is what actually addresses the condition.
Frequently Asked Questions
At what age is a cat considered senior?
Cornell's Feline Health Center now places cats in the "older" category at 12 to 14 years, a change from the 8-year marker used in the past. Some cats show early joint discomfort before that age, so watch behavior, not just the calendar.
How common is arthritis in cats?
Very. Over 90% of cats show radiographic evidence of degenerative joint disease as they age, per NC State's Comparative Pain Research Center — far more common than most owners realize, mostly because cats hide it so well.
How often should a senior cat see the vet?
Healthy seniors: once a year for a full geriatric exam, plus a smaller mid-year checkup. Geriatric cats or those with a diagnosed condition: every six months. Any new symptom warrants a visit regardless of schedule.
What are the earliest signs my cat is aging?
Hesitating before jumping, choosing lower resting spots, grooming less (especially the hindquarters), sleeping more, and any change in litter box habits, appetite, or thirst.
Do joint supplements actually work for cats?
They can support comfort and mobility as part of a broader plan, but they're support, not treatment. A vet visit to confirm what's actually going on comes first.
