Cat Chronic Pain Recognition: Beyond the Hiding Instinct

Cats are evolutionary masters at hiding pain, making recognition of chronic pain in cats a critical veterinary and owner skill that directly determines whether suffering cats receive appropriate relief.

Key Facts

Cats evolved to conceal pain as weakness - pain expression is minimized to avoid predator attraction
Feline Grimace Scale (FGS) uses facial expressions to objectively score pain in cats
FGS parameters include ear position, orbital tightening, muzzle tension, whisker change, and head position
Chronic pain behavioral signs include reduced grooming, hiding, decreased activity, and altered gait
Arthritis is severely underdiagnosed in cats - studies suggest 90% of cats over 12 have radiographic changes
Reduced jumping, reluctance to use litter box, or decreased interactive play often indicate pain
Gabapentin, buprenorphine, and meloxicam are commonly used pain management options in cats
Monthly cat mobility questionnaires completed by owners reliably detect changes in pain status
NSAIDs require careful dosing in cats - cats metabolize drugs differently from dogs and humans

Welfare Considerations

The evolutionary success of pain concealment in cats has created a welfare catastrophe in domestic settings: millions of cats live with untreated chronic pain because their suffering is invisible. The development and validation of the Feline Grimace Scale represents a breakthrough - a tool that allows systematic, objective pain assessment. Owners who learn to observe subtle behavioral changes rather than waiting for obvious signs become effective pain detectors for their cats. Arthritis management in cats is one of the most underprovided veterinary services relative to need.
