Companion Cat Pain Assessment Grimace Scale

The Feline Grimace Scale provides a validated tool for assessing acute pain in cats through facial action units, improving pain recognition and treatment.

Key Facts

The Feline Grimace Scale uses five action units: orbital tightening, nose/cheek flattening, whisker change, ear position and head position
Validated studies show high reliability between trained scorers using the scale
The scale is designed for cats in clinical settings with moderate to severe pain
Training improves scoring accuracy for veterinary professionals and owners
Earlier and more accurate pain recognition using the scale improves analgesic prescribing

Welfare Considerations

The Feline Grimace Scale represents a significant advance in feline pain recognition by providing objective criteria for a species notorious for masking pain. Wider adoption in veterinary practice and training of cat owners to recognise facial pain indicators improves welfare outcomes.
