The disappearances are longer. She's not jumping to her favorite perch. She's not crying or limping, so she must be fine — right? Here's the most important thing to understand about cats and pain: the absence of obvious distress does not mean the absence of pain.
Your cat has always been independent. She disappears under the bed for an afternoon, emerges for dinner, and finds her spot on the windowsill before curling up for the night. It's just her nature, you tell yourself. But lately, the disappearances are longer. She's not jumping to her favorite perch anymore. When you go to pet her, she tolerates it briefly and then retreats. Something feels different — but she's not crying or limping, so she must be fine.
This is one of the most important things to understand about cats and pain: the absence of obvious distress does not mean the absence of pain. In fact, hiding and withdrawing are among the most reliable signs that your cat is hurting.
Why cats hide their pain so effectively.
The instinct to conceal vulnerability is even stronger in cats than in dogs. As both predators and prey animals, cats evolved to appear healthy and capable at all times. Showing pain — vocalizing, moving differently, acting distressed — signals weakness to potential predators. So cats don't.
Instead, they minimize. They slow down. They find quiet spots away from activity. They stop doing things that hurt and avoid interactions that might jostle a painful area. From the outside, this can look like aloofness, preference for solitude, or simply “cat behavior.”
The International Cat Care organization notes that cats are so effective at masking pain that even veterinarians can miss it — which is why knowing the subtle behavioral signs is so valuable for the people who know their cats best.
The subtle signs your cat is in pain.
Increased hiding or withdrawal. A cat who spends significantly more time in isolated spots — under the bed, in a closet, behind furniture — is often managing pain by limiting social interaction and unpredictable touch. If the frequency or duration of hiding has increased, pay attention.
Reduced jumping and climbing. Cats are natural jumpers. A cat who no longer leaps to her favorite shelf, the countertop, or your bed isn't necessarily being lazy — she may be calculating the pain cost of the jump and deciding it isn't worth it. Watch for her sitting at the bottom of her cat tree and looking up without jumping.
Changes in grooming. Cats in pain often groom less because twisting and reaching the affected area hurts. A coat that's becoming dull, matted, or unkempt — especially around the lower back, hips, or tail base — can signal joint pain or spinal discomfort. Conversely, some cats over-groom (lick obsessively) at a painful area.
Litter box issues. Arthritis in the hips or spine can make stepping into and squatting in a litter box genuinely painful. If your cat is eliminating outside the box but seems otherwise healthy, joint pain — not behavioral defiance — may be the explanation. Switching to a low-entry litter box can help immediately.
Changes in facial expression. Research published in journals of veterinary science has shown that cats in pain display subtle facial changes: ears slightly flattened or pulled back, eyes partially closed, whiskers pulled back, and a tight or tense expression around the muzzle. These changes are easy to miss but consistent across individual cats.
Reduced appetite or slower eating. Pain is a stressor, and stress suppresses appetite. A cat eating more slowly or with less enthusiasm than usual may be dealing with discomfort that makes even mealtimes feel like effort.
Irritability when touched near specific areas. A cat who flinches, hisses, or moves away when you touch her lower back, hips, or legs is signaling that those areas hurt. This is worth noting and mentioning to your vet.
Cat arthritis: more common than most people realize.
Feline osteoarthritis is far more prevalent than the average cat owner knows. Studies suggest that up to 90% of cats over the age of 12 show radiographic (X-ray) evidence of arthritis — and many cats as young as 6 or 7 have measurable joint changes. Yet the diagnosis is frequently missed because cats hide the signs so well.
The joints most commonly affected in cats are the elbows, hips, stifles (knees), and spine. When these joints are inflamed and worn, the movements that were once effortless — jumping, climbing, turning sharply during play — become painful. The cat adapts by doing less, hiding more, and interacting differently. What looks like a personality shift in a middle-aged or senior cat is often a response to unmanaged pain.
What you can do at home.
Vet evaluation first.
If you've noticed reduced activity, less jumping, or more hiding, a vet exam is the right first step — with X-rays if arthritis is suspected. There are prescription feline pain relief options designed for cats, who metabolize drugs very differently from dogs and cannot safely take most human or dog pain medications.
Lower the barriers.
Ramps or steps to favorite perches, low-entry litter boxes, and food and water bowls at a comfortable height dramatically reduce the daily pain burden for an arthritic cat. Small changes, real difference.
Provide warmth.
Cats with joint pain seek warm spots intuitively. A self-warming mat or a cozy heated bed in a quiet area can reduce joint stiffness and make rest more comfortable.
Consider joint supplements.
Omega-3 fatty acids (fish oil), glucosamine, and veterinary-formulated joint supplements can support cartilage health in cats. Always consult your vet first — cats have specific nutritional needs.
Gentle enough for the one who hides.
Red light therapy won't replace your vet's diagnosis or a prescription plan. For a cat whose pain is keeping her in hiding, it offers a quiet, drug-free way to reduce the discomfort that's making her withdraw.
What the research shows
Red light therapy — the same technology used in veterinary laser therapy — works by delivering targeted wavelengths of light that penetrate into joint and soft tissue, where they reduce inflammation, stimulate cellular repair, and improve circulation. Research supports its use for feline arthritis and musculoskeletal pain, and many cat owners report visible improvements in their cat's mobility and social behavior after consistent sessions.
VCA describes therapeutic laser as a noninvasive option used for osteoarthritis and musculoskeletal conditions — and feline patients are part of that clinical picture.

How to use it at home
Because the device is quiet and non-invasive, most cats tolerate sessions well — especially when introduced gradually in a calm, familiar environment. Start where she already rests, hold the device against the coat over the sore joints your vet has identified, and let the 10-minute timer run.
Skip these areas entirely: the eyes, open wounds or incisions until your vet clears them, any cancerous or suspicious lesion, the thyroid area, and a pregnant abdomen.
Yugo Red Light Therapy Device
Handheld dual-wavelength cold laser — true nonthermal, designed for use with both dogs and cats. 650 nm red light is absorbed near the surface; 808 nm near-infrared penetrates deeper into soft tissue. Built-in 10-minute timer. FDA 510(k)-cleared (K241057)*.
*FDA 510(k) K241057 applies to specified human-use indications. Veterinary uses are not included in this clearance.
Bring her out of hiding.
Clinic laser sessions mean carriers, car rides, and $50–100 per visit — hard on a cat who's already withdrawing. The Yugo device brings the same class of true nonthermal cold laser home for a one-time $350, in the calm place she already trusts.
Key points, pinned for later.
For the next time she skips the jump to the windowsill and you wonder if it means something.
Is my hiding cat in pain?
Quite possibly. Increased hiding, reduced jumping, grooming changes, litter box misses, and irritability when touched are among the most reliable signs of feline pain — usually arthritis, which shows on X-rays in up to 90% of cats over 12. Cats mask pain by design, so trust the behavior change and book a vet exam.
Never medicate a cat yourself
Cats metabolize drugs very differently from dogs and cannot safely take most human or dog pain medications. Pain relief for cats starts at the vet, full stop.
The quiet checklist
Longer hiding, skipped jumps, dull or matted coat, litter box changes, tense face, slower eating, flinching at touch.
Cats over 12 with OA on X-ray
Feline arthritis is the norm in senior years — and routinely missed.
Comfort is buildable
Low-entry litter box, ramps to perches, warm beds, vet-approved supplements — plus quiet red light therapy sessions at home.
Searched at midnight, settled here.
