At the Barcelona Zoo, specialized care is now provided for elderly animals, including Susi and Bully, two aging African elephants. This shift began in recent decades, as zoos worldwide redefined their mission from public exhibition to conservation and education. These efforts have led to improved conditions, such as larger enclosures and better veterinary support. In December, the zoo mourned the loss of Yoyo, a 54-year-old elephant who had been a long-time companion to Susi and Bully. Following her death, the zoo began a collaborative study with the University of Barcelona to observe the psychological effects of grief on unrelated elephants — a first-of-its-kind initiative. According to experts, animals that have spent their lives in captivity or circuses often cannot return to the wild, and lifelong care becomes imperative.

To address this need, zoos are now implementing geriatric programs with meticulous attention. These include routine health assessments, arthritis treatments, and customized diets for animals without molars. The Barcelona Zoo offers a soft, sand-covered floor to ease joint pressure and administers daily foot care for its senior elephants. Experts from the World Association of Zoos and Aquariums emphasized that advancements in veterinary medicine have extended animal lifespans, making age-specific support indispensable. Facilities in the United States, such as those in Baltimore and Baton Rouge, have also adopted similar approaches. This evolution in zoo management reflects a growing commitment to animal welfare, ensuring older animals receive dignified care in their final years.
