So hard to shut down a zoo - very few places for the animals to go. But other zoos and zookeeping associations could definitely aid in getting these animals to other places. There are lots of animal rescue places out west, as well (more space - Utah has several and there's a big cat rescue here in California). There's also a teaching zoo out here that specializes in zoo rescue animals.
It is infuriating that this zoo doesn't seem to have security. And yes, sickening.
Fortunately, tiny monkeys are way less dangerous than a chimp - but four chimps were killed (murdered) because Swedish authorities apparently don't know what a tranquilizer dart might be:
Officials at a Swedish Zoo have managed to get three chimpanzees who had broken out of their enclosure back into a secure space, but four others were shot dead.

I was shocked by this and still am.
