UNITED NEWS INTERNATIONAL (UNI) — The last male northern white rhino may be living his final days but his caretakers shared a small bit of good news.

They told the BBC the 45-year-old rhino named Sudan seemed to feel slightly better on Monday, March 5.

The elderly rhino enjoyed a mud bath in the rain.

Sudan’s spa day came less than a week after caretakers at Kenya’s Ol Pejeta Conservancy announced the rhino’s deteriorating health.

They said Sudan suffers from an “age-related” infection in one of his legs.

His caretakers said, “We are very concerned about him — he’s extremely old for a rhino and we do not want him to suffer unnecessarily.”

Sudan and two northern white rhino females also at the sanctuary are the last of their kind. Attempts to breed Sudan have been unsuccessful.

All three rhinos are under constant armed guard to protect them from poachers.
