Heather, Cara, and I scoured the city looking for a vet who would look at El Mono, but because of strict laws against the treatment of primates, no vets were will wanting to look at him or even give us advice. We walked around the city with El Mono for what seemed like hours going from vet to vet. After receiving a tip from the third vet, we took a taxi over to the other side of the city to our fourth vet who said he would look at him.
For negligible sum, I was able to pay for El Mono to get some medicine. With Cara translating, the vet informed me that the monkey was sick and had been malnourished and mistreated. He was 6-7 months old and remarkably underweight. We got the monkey the shots and medicine he needed and took the taxi home.
Later, Cara and I were able to get in contact with an Bolivian animal rescue organization who were willing nurse the monkey back to health before releasing him back into the jungle in a wildlife park. A few hours later, a representative from the organization came by to pick El Mono. It was a sad parting, but I felt really good that El Mono was going to be taken care of and eventually taken back to his home in the jungle. Thus happily ends a saga of a sad monkey.
