The Feline Grimace Scale provides an objective tool for assessing acute pain in cats. Wider adoption in clinical settings is improving feline pain recognition and treatment.
For decades, cat pain went undertreated partly because assessment was subjective and inconsistent. A cat in pain frequently adopts a withdrawn, quiet posture that owners and clinicians misread as calm. The development and validation of the Feline Grimace Scale gives clinicians and owners a structured, objective framework for recognizing pain through facial expression analysis - the same approach used successfully in other species. Wider training in FGS use among veterinary professionals represents a direct welfare improvement for millions of cats globally.
