Not jumping or playing like they used to

What this tends to look like

• Stopped jumping onto a worktop, windowsill, bed or sofa they always used
• Takes the route in stages now, using a chair as a halfway step
• Sleeps more, plays less, and is generally less involved in the household
• In cats, sometimes a less tidy coat because grooming certain areas has become uncomfortable
• In cats, occasionally missing the litter box edge, or avoiding a box with high sides
• No limp at all, which is precisely why it gets attributed to age

What is usually going on

Cats almost never limp with arthritis, and that single fact is why feline arthritis is so widely missed. Radiographic surveys have repeatedly found degenerative joint change in the large majority of cats over about ten years old, while very few of them are ever presented for lameness. What owners notice instead, if anything, is a cat who has quietly stopped getting up somewhere, or who takes the journey in two hops now. Dogs do a version of the same thing: no limp, just less.

The reason this matters is that reduced activity is not a mild sign. It usually means the animal has already decided a movement is not worth what it costs, and that decision generally comes after months of discomfort rather than at the first twinge. It is also self-reinforcing, because less movement means less muscle, which means more load on the joint.

It is worth being clear that this is one of the highest-value things to take to a vet, because feline pain relief options have improved considerably and are underused, largely because nobody brought the cat in. Environmental changes matter more here than products do: a set of steps to the favorite spot, a litter box with a low entry, food and water at floor level. Those often produce a visible difference within a week, which supplements will not.

What you can do at home

• Build a route rather than removing the destination. A stool or a step to the windowsill keeps them using it
• For cats, a litter box with a low entry, or one side cut down. High sides are a common and easily fixed problem
• Put food, water and beds where they do not have to jump or climb to reach them
• Warm, soft, easily accessible beds, and more than one so they are not choosing between comfort and company
• Non-slip surfaces where they land, because a bad landing teaches them not to try again
• Film or list what they have stopped doing, then review the list monthly. It is a better measure than how they look

What progress should look like

How long to give this before you conclude it is not working.

• First weekSteps, ramps, low-sided litter box and floor-level food. Often the fastest visible improvement of anything on this page.
• Two to four weeksWatch whether they resume one or two of the activities on your list. That is your real outcome measure.
• Four to eight weeksOmega-3 could reasonably show something by here. Joint supplements need longer still.
• OngoingAsk about prescription pain relief, particularly for cats. It is the single most underused option in this situation.

When to stop and call your vet

• Weight loss, or a coat that is deteriorating, which points beyond joints
• Any cat over ten who is markedly less active, which deserves a proper senior workup
• Confusion, night restlessness, or getting lost in familiar rooms, which is a different problem
• Sudden inability to jump at all, rather than gradual reluctance
