Almost hourly, the zoo provides the animals with frozen fruits and large red syrup ice cubes to cool them down and lessen their stress.

The zoo’s star attractions include Joy, an orangutan born to the late celebrity orangutan Mike and his mate Susu who got “married” amid much fanfare more than two decades ago.

Lop Buri Zoo director Banphot Amyoo said that besides the frozen snack treats, zoo workers had also installed water sprinklers around the compound to cool the animals down.
