Pain is not just a human experience; animals, too, sense and respond to harm, though their conscious pain may be harder to prove. Chickens and rats will self-medicate with painkillers, while octopuses and hermit crabs make decisions that suggest awareness of suffering. While vertebrates are legally protected from unnecessary pain in many countries, invertebrates like crabs and octopuses often are not, even as evidence grows that some can feel more than simple reflexes. Understanding how animals experience pain challenges ethical choices and urges a deeper responsibility for their welfare.
