貓關節炎：隱藏的疼痛
高達90%的12歲以上貓有關節炎，但大多數未確診。了解微妙跡象和現代治療選擇。
Arthritis (osteoarthritis) is one of the most underdiagnosed conditions in cats. Studies show that up to 90% of cats over age 12 and 60% of cats over age 6 have radiographic evidence of arthritis. Because cats are masters at hiding pain and rarely limp visibly, most owners don't realize their cat is suffering. Recognizing the subtle signs and seeking treatment can dramatically improve your cat's quality of life.
- Up to 90% of senior cats have arthritis — it is massively underdiagnosed
- Cats rarely limp — instead they reduce activity, avoid jumping, or change behavior
- Signs include reluctance to jump up/down, using stairs less, decreased grooming, and hiding
- Anti-inflammatory medications (NSAIDs) approved for cats can significantly improve comfort
- Environmental modifications — ramps, heated beds, low-entry litter boxes — make a big difference
- Solensia (frunevetmab) is a new monthly injection specifically for feline arthritis pain
Why Cats Hide Arthritis Pain
In the wild, showing pain makes cats vulnerable to predators. This survival instinct means domestic cats rarely show obvious lameness. Instead, they compensate by jumping less, avoiding stairs, sleeping more, and reducing grooming (especially on the hind end). Many owners attribute these changes to "getting old" when they actually indicate chronic pain requiring treatment.
Recognizing the Signs
Key signs to watch for: your cat hesitates before jumping or uses intermediate steps (chair → counter instead of floor → counter), has matted fur on the back or hind legs (reduced grooming), avoids the litter box because the sides are too high to step over, becomes less social or hides more, shows irritability when touched in certain areas, or has stiff movements after resting.
Treatment Options
Treatment is multimodal: pain medication (meloxicam/NSAIDs for cats with kidney monitoring, or the newer Solensia monthly injection), joint supplements (omega-3 fatty acids, glucosamine), weight management (even 5% weight loss reduces joint stress), physical therapy (gentle range-of-motion exercises, laser therapy), and environmental modifications. Solensia (frunevetmab) is a breakthrough — a monthly injection that blocks nerve growth factor, providing significant pain relief without daily medication.
Home Modifications
Small changes make a big difference for arthritic cats: provide pet stairs or ramps to favorite perches, use low-entry litter boxes (cut down the front of a storage bin), place heated beds in favorite sleeping spots (warmth soothes stiff joints), add non-slip mats on slippery floors, and ensure food/water are on the same level as where your cat spends most time. These modifications allow your cat to maintain independence and dignity.
- Your senior cat has stopped jumping to favorite high spots
- Your cat's grooming has decreased, especially on the back or hind legs
- Your cat is having accidents outside the litter box or avoiding it
- Your cat seems less social, hides more, or is more irritable than usual
- Your cat has stiff movements after resting that improve with activity
- You want to discuss pain management options for your aging cat
