Mobility Scoring for Senior Cats: 5 Items, 4 Weeks

A cat that stops jumping onto the counter is not being lazy; it is reporting pain in the only unit it has. The Feline Musculoskeletal Pain Index turns that report into 5 numbers you can compare across months: jump, run, stairs, grooming, and walking. Score each item 0 to 4, once every 4 weeks, and treat a change of 2 points or more on the 20 point total as a reason to book an examination within 14 days, not a reason to wait for the next checkup.

Why a number beats a memory

Owner impressions drift. The same cat that felt slow in March feels normal in June because the decline was gradual, and a 6 month veterinary interval is long enough to hide it. A score fixes 3 things: the same 5 behaviors are judged every time, the direction is visible on paper, and the trend is legible to someone who has never met the cat. Keep the sheets; 3 consecutive scores are worth more in the exam room than 10 minutes of description. The whole routine takes 4 minutes a month and needs 2 tools: a tape measure and a phone.

The 5 items and what each one measures

Use a tape, a stopwatch, and a clicker count rather than adjectives. Jump height in centimeters, stairs climbed in a day, seconds to settle after lying down, minutes of self grooming, and distance walked before the cat stops.

Item	What you measure	Score 0	Score 2	Score 4
Jump	Highest reliable jump, cm	60 or more	30 to 40	0 (floor only)
Run	Bursts of running per day	3 or more	1	0
Stairs	Steps up per day	12 or more	4 to 6	0
Grooming	Minutes of self grooming per day	5 or more	2	0
Walking	Meters before stopping or sitting	20 or more	8 to 10	Under 3

Score 1 and 3 sit between the anchors: use them when the cat is clearly worse than 0 but not yet at the 2 description. Write the raw measurement next to the score, because centimeters and seconds survive a change of veterinarian, and adjectives do not.

Scoring 0 to 4 without guessing

Watch for 30 minutes at the same time of day, ideally 2 hours after a meal and before the evening zoomies. Do not test jump height by tempting the cat onto a high shelf; offer the usual perch and record what it chooses. Score the day, not the best day of the week. If the cat refuses to perform an item at all, that is a 4, not a missing value. A single bad score means little — weather, a house guest, or a 1 day fast can move 2 points — but 2 consecutive scores in the same direction is the finding worth acting on.

The 4 week rhythm and the 3 sheet rule

Score on the same weekday every 4 weeks, 13 times a year. Keep 3 sheets on the fridge: the current one, the previous one, and the one from 12 weeks ago. That stack covers a full quarter and answers the question a 4 minute exam cannot: is this cat losing range slowly or did something change in the last month? Photograph each completed sheet; owners lose paper, and the camera roll is a backup that survives a move or a change of clinic.

What a 2 point change triggers

The total runs 0 to 20. A rise of 2 points over 4 weeks, or a total of 8 or more at any point, means a call within 14 days with the 3 sheets in hand. A single item scoring 4 for 2 months in a row means the same, even if the total looks stable, because a cat that stops grooming and compensates elsewhere still has a problem. A drop of 2 points after starting pain control is a real improvement and justifies continuing for 8 more weeks.

Total score	Reading	Action	Timeline
0 to 2	Normal for age	Keep scoring	Next 4 week mark
3 to 7	Mild change	Video plus weigh	Within 2 weeks
8 to 13	Moderate	Book examination	Within 14 days
14 to 20	Severe	Examination plus radiographs	Within 7 days

The 10 second video that travels well

Film the cat walking toward the camera on a hard floor for 10 seconds, from 2 meters away, at cat height. Add a 5 second clip of the cat getting up from lying down. Three features are readable at that length: stride length, head carriage, and whether the back arches. Vets who cannot see the cat on a good day can still read those 3, and the file travels in a message instead of being described over the phone. Send it 24 hours before the visit so it can be watched twice.

What the score cannot see

A score measures function, not cause. It cannot separate arthritis from a soft tissue strain, nerve pain, or the muscle wasting that follows 6 months of reduced activity. It also misses dental pain, which changes grooming and eating without changing the jump. That is why the score sits beside a weight trend on the monthly weight sheet and a 6 monthly examination: a cat losing 5 percent of body weight while the score improves needs bloodwork, not a higher supplement dose.

Five steps for this month

• Print 3 copies of the 5 item table and tape them at cat height near the fridge.
• Measure jump height once with a tape and write the number, not a word.
• Score today, then circle the date 4 weeks out.
• Film the 10 second walk clip and keep it with the sheets.
• Compare the total with the weight trend, and price the workup at the cost calculator before the visit.

If the cat also misjudges the edge of the bed or walks into doorframes, the problem may be sight rather than joints; the checks in vision loss in senior cats take 5 minutes and rule that out first.
