Pain in Cats: Why It's So Easy to Miss

Most pet owners have a mental image of what a painful animal looks like: limping, crying out, avoiding a sore spot. That image is reasonably accurate for dogs. 

For cats, it's almost entirely wrong. It's also one of the biggest reasons feline pain goes unrecognized and untreated for months or even years.

At Aloha Veterinary Acupuncture, we see this pattern regularly. A cat's owner will mention, almost in passing, that their cat "just doesn't jump on the counter anymore" or "sleeps more than she used to." These aren't personality quirks. Very often, they're the clearest signals we get that a cat is in pain.

The Scale of the Problem

Chronic pain in cats is far more common than most owners realize. According to the Comparative Pain Research and Education Center at NC State College of Veterinary Medicine, over 90% of cats show radiographic evidence of degenerative joint disease as they age. 

Not every one of those cats is in significant pain, but a substantial portion are, and research suggests at least 40% show clinical signs related to that pain.

Despite how widespread it is, feline arthritis remains one of the most consistently underdiagnosed conditions in veterinary medicine. 

The reason isn't that veterinarians aren't looking. It's that cats are extraordinarily good at hiding discomfort, and the signs they do show are easy to interpret as something else entirely.

Why Cats Hide Pain

This behavior isn't stubbornness or stoicism in any human sense. It's instinct. In the wild, an animal that visibly displays weakness becomes a target. Cats retain that survival wiring, and it means they adapt to pain rather than advertise it.

Practically, this means a painful cat rarely limps. Instead of favoring one leg, cats with arthritis typically develop bilateral joint changes, so there's no asymmetry to notice. 

Rather than vocalizing, they simply stop doing the things that hurt. And because these changes happen gradually over weeks or months, they blend into what looks like ordinary aging.

What to Actually Watch For

The most reliable indicators of feline pain are behavioral, not physical. 

Look for changes in what your cat does, not how they move:

• No longer jumping onto counters, windowsills, or furniture they previously accessed easily

• Hesitating before jumping, or breaking a jump into smaller steps

• Using furniture as a "staircase" rather than jumping directly up or down

• Litter box changes, including accidents outside the box, or difficulty getting in and out of a high-sided box

• Reduced grooming, leading to a matted or unkempt coat, or overgrooming one specific area

• Sleeping more, or choosing new sleeping spots that are easier to reach

• Withdrawal from family interaction, hiding, or reduced tolerance for handling

• Irritability, swatting, or hissing when touched in certain areas

• Reluctance to use stairs

• Changes in appetite or weight

  
  

Any single one of these might mean nothing. But a pattern, especially several appearing together, or one that develops gradually over months, is worth investigating rather than accepting as inevitable.

Why Early Recognition Matters

Untreated chronic pain in cats has consequences beyond discomfort. Reduced activity leads to muscle loss, which further destabilizes already compromised joints. Litter box avoidance can become a permanent behavioral issue. 

Withdrawal and irritability strain the relationship between cat and family. And pain that has been present for a long time becomes progressively harder to manage as the nervous system becomes sensitized to it.

The good news is that feline pain is treatable. Options include weight management, environmental modifications (lower-sided litter boxes, steps to favorite perches, warm and accessible bedding), pharmaceutical pain management, and newer therapies developed specifically for cats. 

A multimodal approach, combining several of these, tends to work better than any single intervention.

Where Acupuncture Fits

For cats with chronic pain, acupuncture can be a valuable addition to a broader treatment plan. It works through neurological mechanisms to modulate pain signaling and reduce inflammation, and it's particularly useful for cats who don't tolerate certain medications well or who need additional relief beyond what pharmaceuticals alone provide.

Our mobile veterinary acupuncture services are also especially well-suited to cats. Clinic visits are a significant stressor for most cats, and treating them in their own home removes that stress entirely, which makes for a calmer patient, a more accurate assessment, and a better experience overall.

Trust What You're Noticing

If your cat has stopped doing something they used to do, that observation matters. You know your cat's normal better than anyone, and the subtle shifts you notice are real clinical information.
