INDIANAPOLIS (WRTV) The Indianapolis Zoo announced Wednesday that it had to make a very tough decision recently.The zoo had to say goodbye to Gloria, a 47-year-old white rhinoceros whos been a fixture in the Plains biome for th e past 18 years. The zoo made the announcement in a social media post.Several animals at the Indianapolis Zoo live well into their old age, a result of the dedicated care they receive throughout their lives. This commitment requires caregivers to make difficult but compassionate decisions when an animals quality of life declines and it shows signs of distress.The zoo said Glorias health and mobility declined in recent weeks, and animal care staff noticed she had trouble moving within her habitat. She had not responded to medical treatment intended to make her more comfortable. Following consultations with the zoos veterinary team, staff decided to humanely euthanize Gloria to relieve her suffering.Saying goodbye is never easy, yet animal care staff understand this decision was the kindest and most respectful choice, the zoo said in the post.The zoo says she will remain and icon and invaluable ambassador for white rhinos. Her legacy includes nine calves, nine grandchildren, 17 great-grandchildren and 15 great-great-grandchildren. Glorias granddaughter, Zenzele, and great-granddaughter, Xola, will continue to represent her at the Indianapolis Zoo.It was a privilege to care for Gloria for the past 18 years, the zoo said in the post. ...read more read less
