Companion Cat Pain Recognition and Management

Cats are notoriously effective at hiding pain, making welfare-conscious guardians and veterinarians essential for identifying and treating suffering that would otherwise go unrecognized.

Key Facts

Cats evolved as solitary hunters for whom showing vulnerability could be fatal, driving strong behavioral masking of pain
The feline grimace scale (FGS) was validated in 2019 and provides a reliable non-invasive pain assessment tool for veterinarians and owners
Key grimace scale indicators include orbital tightening, muzzle tension, whisker bunching, ear position changes, and head position lowering
Post-operative pain is frequently undertreated in cats compared to dogs in veterinary practice, representing a systematic welfare gap
Chronic pain from osteoarthritis is estimated to affect over 90% of cats over age 12 but is diagnosed in a fraction of affected animals
Behavioral changes are often the most accessible pain indicator for owners — reduced activity, hiding, altered grooming, and changed interaction
Meloxicam, gabapentin, and buprenorphine are among the most commonly used feline analgesics with evidence for safety and efficacy

Welfare Considerations

Cat pain is one of veterinary medicine most significant welfare blind spots. The combination of stoic behavioral masking, subtle clinical signs, and historical veterinary underuse of analgesia in cats means that millions of cats live with unrecognized and untreated pain. The development of the feline grimace scale has begun to change practice, giving both vets and owners a validated tool that does not require cats to vocalize or show obvious distress. Guardians who learn the subtle signs of cat pain and advocate for analgesic treatment — rather than accepting a lethargic or withdrawn cat as normal — directly improve cat welfare outcomes.

What You Can Do

Learn the feline grimace scale and regularly assess your cat facial expressions for signs of pain
Report any behavior change to your veterinarian — reduced activity, altered grooming, or hiding are potential pain indicators
Advocate for post-operative analgesia for your cat after any procedure — ask specifically what pain relief is planned
Request osteoarthritis assessment for your senior cat and ask about meloxicam or other analgesic options if appropriate
Support veterinary education that normalizes feline pain assessment and analgesic use as standard practice
