Signs of Arthritis in your Cats

Cats don't show pain the way dogs do. They don't limp, cry, or come to you for comfort. Instead, they quietly adjust - doing a little less each day until joint pain has been building for months without anyone noticing.

If your cat seems lazier, less playful, or "just older," look again. What looks like a personality change is often joint pain hiding in plain sight.

Why Cats Are So Hard to Read

Cats are biologically wired to mask pain. In the wild, showing weakness is dangerous. So even when arthritis is significantly advanced, a cat will keep moving, keep eating, and keep appearing comfortable - until they simply cannot anymore.

Studies show that up to 90% of cats over 12 have arthritis changes visible on X-ray, even when their owners have noticed nothing at all. This is not a failure of observation. It is a reflection of how effectively cats conceal discomfort.

Understanding what to look for - and where - changes everything.

The Four Areas Where Joint Pain Shows Up First

Physical signs

These are the changes you can see if you look closely:

• Stiffness after waking or rest - your cat moves slowly for the first few minutes, then loosens up
• Subtle joint swelling around one or more joints
• Muscle loss particularly around the hips and hindquarters
• Reduced grooming - a matted, unkempt coat, especially around the lower back and tail

Cats stop grooming difficult-to-reach areas first. A scruffy lower back or matted tail base is often the earliest visible clue.

Behaviour changes

These are the most reliable indicators of joint pain in cats:

• Hesitation before jumping - pausing, calculating, sometimes backing away entirely
• Failed or shortened jumps - landing lower than intended
• Avoiding surfaces and spots they previously used with ease
• Less interest in play, interactive toys, or chasing
• Hiding more than usual - retreating to quiet, out-of-the-way spaces
• Irritability when touched, especially around the back, hips, or legs
• Overgrooming one specific joint - this is a sign of localised pain

How cats hide pain

This is the category owners most often miss. These are not dramatic signs - they are the quiet ones:

• Walking more slowly than they used to
• Sleeping significantly more
• Resisting being picked up or shifted from a resting position
• Becoming suddenly quieter or less vocal
• Choosing lower spots to rest - the floor instead of the sofa, the sofa instead of the top of the cat tree

A cat that was once always on top of things is now always on the floor. That shift matters.

Mobility changes

Watch how your cat navigates the home:

• Trouble stepping into the litter box - going around it, hovering at the entrance, or missing the box entirely
• Slower stair climbing - pausing on each step, gripping more carefully
• A shorter stride - steps that look smaller and more careful than before
• Hesitation on slippery surfaces - tiles, marble, hardwood floors
• Choosing the long route instead of a quick jump

Any consistent change in how your cat moves through the home is worth paying attention to.

Mild, Moderate, and Severe: What Each Stage Looks Like

Joint pain in cats progresses gradually. Knowing the stages helps you act at the right time.

Mild joint pain

• Occasional hesitation before jumping, but still manages it
• Slightly reduced grooming
• Small changes in activity - resting a little more than usual
• No obvious limping or distress

At this stage, most owners assume it is normal ageing. It is not. This is the best time to intervene.

Moderate joint pain

• Noticeable difficulty jumping onto furniture
• Avoiding high places they once used regularly
• Visible muscle loss around the hips
• Stiffness that is obvious after sleep
• Reduced play and social interaction

Severe joint pain

• Marked stiffness - reluctance to move at all
• Difficulty accessing the litter box
• Poor or absent grooming
• Hiding or becoming aggressive when handled
• Significant muscle wasting

Even at this stage, most cats remain treatable. Comfort and mobility can be significantly improved with the right care.

One Thing Pet Parents Consistently Miss

A drop in jump height is one of the earliest measurable signs of joint pain in cats - and one of the last things owners notice. If your cat used to leap to the top of the wardrobe and now only makes it to the bed, that reduction in jump height is not laziness. It is pain.

Watch jump height over time. It is more reliable than watching for limping.

When to See Your Vet

Book a vet appointment if your cat shows any of the following:

• A consistent drop in how high or how often they jump
• Stiffness lasting more than a few days
• Litter box accidents or hesitation around the litter box
• A coat that has become matted or neglected
• Increased hiding, irritability, or withdrawal from family
• Muscle loss around the back legs or hips
• Any change in movement pattern that has lasted more than a week

The earlier arthritis is identified, the more options there are to slow it down and keep your cat comfortable.

What to Tell Your Vet

Before your appointment, note down:

• When the changes started
• Which behaviours have shifted - jumping, grooming, play, sleep
• Whether stiffness is worse in the morning or after rest
• Any changes in litter box use
• Whether certain surfaces or spots seem harder for your cat now

This information gives your vet a far clearer picture than a clinical exam alone - because many cats mask pain perfectly the moment they walk into a vet clinic.
