Overview
- The zoo confirmed that three lionesses named Mugi, Ichigo and Ruena died on July 28, July 31 and August 2 after falling ill in late July.
- Pathological exams showed generalized dehydration and multiorgan failure in the three animals, and the zoo says heat stress is a likely contributing factor while further tests continue.
- Zoo staff reported that ten of the park’s 16 lions began showing symptoms such as loss of appetite, fatigue and reduced activity from mid-July, and public lion exhibitions were suspended on July 23.
- Veterinarians have moved weakened survivors to a private, climate-controlled lion enclosure, given intravenous fluids and medications, and added localized cooling and industrial fans to the habitat.
- The deaths come during one of Japan’s hottest summers, have drawn criticism from animal-rights groups about captive conditions, and could spur changes in zoo heat protocols as the investigation proceeds.
