Cats often hide discomfort, so small facial changes can be useful observations. The Feline Grimace Scale looks at specific facial action units, including ears, eyes, muzzle, whiskers, and head position.
The Feline Grimace Scale helps owners review these signs in a structured way. It is most useful when the cat is calm and you can observe without disturbing them.
What the scale reviews
| Facial area | What to observe | Practical tip |
|---|---|---|
| Ears | Forward, slightly apart, or flattened | Compare with normal relaxed ears |
| Eyes | Open, narrowed, or squinting | Look during quiet rest |
| Muzzle | Relaxed or tense shape | Avoid judging from one photo |
| Whiskers | Relaxed or pushed forward | Compare both sides |
| Head position | Above, level, or below shoulders | Watch posture during rest |
How to observe your cat
Do not force your cat into a position. Observe from a short distance when they are resting. If you take a photo, use it as a reference, but do not rely on one angle alone.
Stress can also change facial expression and posture. The Feline Stress Calculator may help if hiding, appetite changes, or household stress are also part of the picture.
What the result can help with
The score can help you decide whether a change is worth tracking and mentioning during a visit. It can also help compare before and after a known event, such as a dental issue, injury, or procedure.
For long-term care, weight and body condition may also matter. The Cat Weight Calculator (BMI) can support broader tracking.
Why one photo is not enough
A single photo can be misleading. Cats may squint because of light, turn their ears because of sound, or lower their head while resting. It is better to observe several quiet moments and compare them with your cat's normal relaxed expression.
If you use photos, take them without forcing the cat to move or pose. Natural resting images are more useful than stressed or handled images.
Combine facial cues with behaviour
Facial cues are only one part of the picture. Appetite, hiding, jumping, grooming, litter box use, and social behaviour also matter. If the grimace score seems higher than usual, check whether other habits have changed too.
This broader context helps you avoid overreacting to one expression while still noticing a pattern that deserves attention.
When the scale is most useful
The scale is most useful when you know your cat's normal relaxed face. Some cats naturally squint more than others. Some hold their ears differently when listening. Comparing your cat with their own normal expression is more helpful than comparing them with another cat.
Try observing during quiet rest in the same location over a few days. If the same facial changes appear along with hiding, reduced appetite, or lower activity, the score becomes more meaningful.
Note: Grimace scoring can help track visible comfort signs, but pain concerns should be discussed with a veterinarian.
