The Grivets would probably go insane in these tiny cages. Harsh metal, pounding noise on the roof when it rains, little enrichment, no opportunity to get away from bullying monkeys. Ouch.
@snowleopard I went out of a sense of morbid curiosity (knowing the zoo wouldn't be good), but I was so disheartened by the state of the husbandry and some of the animals. There are many enclosures and animals that I was so depressed by, that I didn't even take photos, especially those for the large carnivores
