The observation that feels too vague to mention
Cats rarely limp the way dogs do. What owners tend to notice instead is small and hard to put into words: a cat that takes the stairs in two stages, or stops landing on the windowsill it used to reach in one jump.
It is easy to dismiss that as ageing. It is also easy to feel you have nothing concrete to tell the vet. A 2023 blinded study asked whether those vague impressions correspond to anything measurable — and found that they do.
What the research found
Researchers compared 30 cats whose owners had noticed early mobility changes with 27 cats whose owners had not (57 cats total). Owners completed questionnaires before a home visit. At the visit, each cat had an orthopaedic examination. The study was blinded.
The two groups were similar in age category, breed, sex, temperament, and body condition score — so the differences were not simply explained by the first group being older or heavier.
- Cats with owner-noticed mobility changes scored significantly worse on the Feline Musculoskeletal Pain Index (P = 0.003).
- Total pain scores on examination were higher (P < 0.0001), as were crepitus (P = 0.002) and joint thickening (P = 0.003).
- Those cats had 14 times the odds of disease affecting both sides of the body (P = 0.005).
The authors conclude that both the pain index and orthopaedic examination could distinguish cats with early owner-reported mobility signs from cats without them — and that recognising impairment earlier opens the door to interventions aimed at slowing progression.
What it can't tell you
Fifty-seven cats is a small study. The design is strong (blinding and a control group matter), but an odds ratio of 14 from a sample this size carries wide uncertainty. Owners who enrol in a home-visit study are engaged; the finding may not transfer to every household.
This study also cannot tell you what share of cats with joint disease have owners who notice. It only shows that when these owners did notice, examination found more. Slowing down has many causes. An observation is a reason to report, not a diagnosis.
Signs that can't wait
Call a vet or emergency clinic now
- Sudden inability or refusal to walk, jump, or bear weight on a limb
- Cry of pain when touched or moved, or marked aggression that is new and tied to handling
- Collapse, severe lethargy, or a cat that will not move and seems distressed
- Suspected trauma (fall, hit by something, fight) with any of the above
Same-day or next-day vet
- A clear, recent change in jumping, stairs, or litter-box entry that is getting worse over days
- Limping that persists more than a day, or favouring one side
- Avoiding the litter box after previously using it, when a high-sided box or painful entry could be involved — and any straining with little or no urine (especially in a male cat) is an emergency, not a mobility issue alone
Worth booking an appointment
- Gradual changes over weeks: lower jumps, staged stairs, unkempt patches of coat, new sleeping spots on the floor, less tolerance of being picked up
- You are not sure whether what you are seeing is "just age" — that uncertainty is exactly when a dated note helps the clinic
What to keep in your cat's record
- Which jumps changed — which surfaces, and whether your cat now goes in stages or picks lower routes
- Stairs — pace and pattern, dated when you first noticed
- Litter box — entry/exit difficulty; note if a high-sided box became harder
- Grooming — patches that look unkempt or areas your cat seems to avoid reaching
- Sleeping spots — a favourite high perch abandoned is information
- A short phone video of your cat approaching a jump it used to make easily — often more useful than any description
How PAWai fits in
PAWai does not assess mobility, score pain, or diagnose joint disease. The measurements that mattered in this study were a validated pain index and a hands-on orthopaedic examination — both belong to your veterinarian. What PAWai can hold is the dated list of small observations in your own words, so "I think he's slowed down a bit" arrives as a record the clinic can use.
If your cat suddenly cannot walk, cry when moved, or seems severely distressed after a fall, don't open an app. Call a veterinarian.
