At the Barcelona Zoo, special care is now given to elderly animals like Susi and Bully, two older African elephants. This change began in recent decades when zoos around the world started shifting their focus from showing animals to protecting them and teaching people about wildlife. Because of this, many zoos now have bigger living spaces and better medical care. In December, the zoo lost Yoyo, a 54-year-old elephant who had been close to Susi and Bully. After Yoyo’s death, the zoo partnered with the University of Barcelona to study how elephants feel grief, even when they are not related — a project that is the first of its kind.

Zoos are now creating special programs for older animals. These include regular health checks, treatment for arthritis, and special food for those without teeth. The Barcelona Zoo uses soft sand floors to reduce joint pain and provides daily foot care for its elderly elephants. Experts say that because veterinary care has improved, animals live longer and need more age-specific help. Zoos in Baltimore and Baton Rouge have also started using similar methods to support older animals.
