Cats almost never advertise joint discomfort with a limp. A cat who hurts adapts instead, quietly redesigning daily life around what still feels manageable, and each small adaptation looks innocent on its own: laziness, age, fussiness, mood. Read together over weeks, the edits form one of the clearest patterns in feline care, and catching it matters, since discomfort that is recognised can be discussed with a vet, while discomfort that is mistaken for personality simply runs on unmanaged.
Jumping and Climbing Shrink First
Height is usually the earliest casualty. A cat who once took the wardrobe in one movement starts jumping lower, hesitating at the edge before committing, scrabbling where she used to land cleanly, or routing herself halfway up via a chair or step she previously ignored. Counters, windowsills and favourite perches get visited less, then abandoned, and the cat's world quietly flattens toward the floor. Sleeping places migrate downward too, from wardrobe tops to sofa seats to a cushion on the floor, in a progression owners rarely connect with discomfort. Watch stairs too: a bunny-hopping descent, one step at a time with both hind feet together, or a new reluctance to come down in the morning all belong on the list.
Grooming, Scratching and Claws Report the Reach
Grooming requires spinal flexibility a stiff cat no longer has. The coat over the lower back, hips and hindquarters grows dull, flaky or matted in a cat who grooms her front half immaculately, because that is the half she can still reach. Scratching, which stretches the spine and maintains the claws, fades with it, so claws thicken and overgrow, sometimes curving toward the pad in older cats who have almost stopped scratching. A cat asking for brushing she used to perform herself is frequently a cat showing you the map of where she can no longer bend.
Litter Tray and Daily Routine Clues
Stepping over a high tray side can hurt enough to change toilet habits in a fastidiously clean animal: perching awkwardly half-in, missing the edge, choosing the floor beside the tray, or suddenly preferring the lower-sided tray in another room. Stiffness after rest is another tell: the first movements off a long sleep look slow and careful, then ease as the cat warms into motion, a pattern owners often blame on sleepiness. Play sessions shorten, toys get watched rather than chased, lap time may drop if being lifted or settling is uncomfortable, and some cats grow irritable when stroked along the back or picked up, a response change easily misread as grumpiness.
What to Do With the Pattern
Write the changes down with rough dates rather than deciding from one observation: cats have off days for many reasons, and the vet's question will be how long and how steadily. Short phone videos of the hesitation before a jump, the stair descent or the stiff first steps after a nap are genuinely useful at the appointment. This is a signs-and-routing matter: do not start supplements or any medication on the strength of a pattern, since the vet needs to examine the cat, consider other causes of the same signs, and agree what, if anything, should change at home. Ramps, steps and a low-sided tray are kind household adjustments you can discuss at the same visit, and their effect, noted week by week, tells the vet plenty.
Month-by-month notes turn a vague sense that a cat has slowed down into a dated record of exactly what changed, and in KinsLe the Pet Passport keeps that mobility timeline ready to open at every appointment.
