The tigers are being cared for at a wildlife conservation facility in Quang Tri Province after being transferred from Pu Mat National Park in 2022 following their rescue from an illegal wildlife trafficking case in Nghe An Province.
Conservation staff said the animals had adapted well to their captive environment thanks to regular health monitoring and carefully managed diets.
Caretakers said prolonged heat could affect tigers, which struggle to release body heat because of their thick fur. During hot weather, the animals often reduce movement and seek water or shade to cool down.
To help the tigers stay cool, the conservation centre maintains clean bathing pools, fresh drinking water and misting systems around the enclosures, while staff closely monitor the animals and provide enrichment activities to reduce heat stress.
One cooling measure involves adding ice blocks to feeding routines, with some tigers playing with the ice before eating. Caretakers said the activity encouraged movement and reduced boredom in captivity.
The tigers were also seen playing with plastic containers, tree branches and other objects placed inside their enclosures as part of efforts to recreate more natural behaviours.
Phong Nha-Ke Bang National Park’s conservation centre currently rescues and cares for more than 60 wildlife species, including many rare and endangered animals.
