Cats conceal chronic pain with extraordinary effectiveness, meaning significant welfare problems often go unrecognized and untreated for months or years.
The systematic concealment of pain by cats represents one of the most significant challenges in companion animal welfare. A cat experiencing significant chronic arthritis pain may continue to eat, groom partially, and interact with owners while experiencing daily discomfort that goes entirely unrecognized. The owner perceives a cat that is "just getting old and slowing down" rather than one in treatable pain. The welfare implications are enormous: millions of cats globally are experiencing chronic, unmanaged pain in their homes, not due to owner neglect, but due to the combination of natural pain concealment and insufficient veterinary assessment.
