A video taken at the Care for Wild Africa Rhino Sanctuary in Mpumalanga, South Africa, and posted to YouTube on May 15 shows the adorable moment a trio of rhino calves begin crying when their breakfast ran out. The rhino calves were all orphaned by poachers and are currently being cared for by the sanctuary.The video was shared on Reddit by Nkandla, who responded to comments about the calves. According to Nkandla, the calves are fed their milk every three hours and weigh more than 400kg, or 880 pounds. They also wrote that the calves are emotionally scarred by their experience watching their mothers die from poaching, and suffer from nightmares. Credit: YouTube/Working With Rhinos
