Tragic news cames from Berlin Zoo (DE): Indian Rhino bull Yodha had suffered from severe bowel constipation since Saturday 29 July 2017. His conditions worsened on Sunday and the Vet team made the hard decision to put him to sleep: there was no chance of recovery.
Yodha was 31 years old, a venerable age for an Indian Rhinoceros. During the past months the bull suffered of muscle pains and bad teeth; he had cataract,too.
