I worked with monkeys that lived outside in cages. The cages were probably 50'x20'x12' (LxWxH). There were hundreds of monkeys per cage. Veterinary students would be observing them often. I was told to not disturb them or interact with them in any way. That's quite impossible. They're keenly aware of where you, other people, and even where all the squirrels are at all times. They're mini- or pre-people, if you will. If you think your dog is smart, these animals are smarter.

I wouldn't say they were abused or neglected but it is a sad twist of fate that these wild animals end up being cooped up in cages in the Davis heat, which is close to my personal definition of oppression.

I honestly felt bad for them all the time and I did meaningless work for the center so I moved on.
