Cats are even more stoic than dogs and chronic pain conditions including arthritis are massively underdiagnosed.
Chronic pain in cats represents a massive hidden welfare problem. The instinct to mask vulnerability means cats continue normal-seeming routines while experiencing persistent pain. Arthritis prevents cats from grooming difficult areas leading to secondary coat problems. Dental pain alters eating behaviour but owners often attribute this to preference rather than pain. The widespread underdiagnosis means millions of cats live with untreated chronic pain.
