Why is this helpful?
Cats are notorious for hiding pain, making it difficult for owners to know when their pet is suffering. The Feline Grimace Scale is a scientifically validated tool that looks at five key facial features (Action Units) to objectively measure acute pain. By understanding these subtle changes in ear position, eye shape, muzzle tension, and more, you can determine if your cat needs immediate veterinary attention.
Assess your cat's facial expressions to identify signs of pain using the 5 Action Units.
Disclaimer:
This scale is a visual tool to help identify signs of pain and does not replace a veterinary examination. Cats instinctively hide pain. If you suspect your cat is hurting, or if their score is 4 or higher, contact your vet immediately.
