Cat Chronic Pain: Recognition and Management in Companion Cats

Chronic pain in cats is dramatically underdiagnosed due to the species' masking of pain signals. Improved recognition tools and evidence-based treatment approaches are transforming feline pain management.

Key Facts

Degenerative joint disease affects over 90% of cats over age 12 but is diagnosed in less than 4% of feline patients
Cats evolved to mask pain as a survival mechanism — signs are subtle behavioral changes rather than obvious vocalization
The Feline Grimace Scale, validated in 2019, allows reliable pain assessment from facial muscle changes
NSAIDs have historically been more dangerous in cats than dogs due to limited hepatic glucuronidation, but newer options are now available
Meloxicam at low doses has demonstrated safety with long-term use in cats with intact kidney function
Feline joint pain causes reduced grooming, decreased jumping height, sleep location changes, and litter box avoidance
Multimodal pain management combining medication, weight management, environmental modification, and physiotherapy gives best outcomes

Welfare Considerations

Feline chronic pain management represents one of the most important welfare frontiers in veterinary medicine. The scale of undertreated pain in cats is extraordinary: degenerative joint disease is essentially universal in older cats, yet most receive no pain management because their owners do not recognize the subtle behavioral changes that indicate chronic discomfort. Cats with joint pain stop jumping to favorite high spots, spend more time sleeping, reduce their grooming range (often leaving their back and hindquarters unkempt), and may miss the litter box rather than step over high sides. These changes accumulate gradually and are easy to attribute to aging rather than treatable pain. The development of validated feline pain assessment tools and safer analgesic options has created real opportunities to improve welfare for the millions of cats living with untreated chronic pain.

What You Can Do

Learn the feline signs of chronic pain — behavioral changes rather than vocalization are the primary indicators
Use the Feline Grimace Scale or similar validated tools to assess your cat for signs of pain
Discuss pain management options with your veterinarian for any cat over age 10 showing mobility changes
Provide environmental modifications for painful cats — lower-sided litter boxes, ramps, and accessible sleeping spots
Monitor body condition regularly — obesity significantly worsens joint pain and is manageable
Ask your veterinarian about newer analgesic options specifically developed for feline chronic pain
