Overview
- Zoo Berlin confirmed the death of Kathi, 50, and said the Leibniz Institute for Zoo and Wildlife Research is determining the cause.
- The hippo had seemed weak in recent days and spent unusually long periods in the water, according to the zoo director.
- Veterinarians had been closely monitoring age-related arthrosis in her limbs.
- The herd now comprises Bouli, Nala, and Willi, who was born in 2025.
- Reaching 50 is exceptional for this species compared with the wild, where poaching and habitat loss often shorten lifespans.
