Chronic Pain Recognition in Cats

Cats are expert pain maskers; validated facial grimace scales and behavioral indices now enable owners and vets to identify and treat chronic pain that was previously missed.

Key Facts

An estimated 40-90% of cats over age 10 have radiographic evidence of arthritis
The Feline Grimace Scale (FGS) reliably distinguishes cats in pain from pain-free cats
Subtle behavior changes including reduced grooming, changed litter box use, and reduced play are early pain indicators
Multimodal pain management including NSAIDs, gabapentin, and environmental modification improves feline chronic pain outcomes
Many cats with treatable chronic pain are euthanized for 'behavior problems' that are actually pain expression

Welfare Considerations

Chronic pain in cats is one of the most significant underdiagnosed welfare problems in companion animal medicine. Cats evolved to hide pain as a survival mechanism, making their stoic presentation a welfare liability when living with humans who assume that quiet cats are comfortable cats. The Feline Grimace Scale and behavioral pain assessment tools have provided validated methods for detecting pain that was previously invisible to most observers. Early recognition and treatment of chronic pain - particularly arthritis in older cats - can extend comfortable, high-quality years of life for animals that would otherwise suffer invisibly.
