Various materials are used to tether the captive primates (chains, rope, wire and belts), most often fastened around their waist but sometimes around their neck or wrist. The tethers are short allowing very restrictive movement, confining the monkey to a small patch of ground or to a tree. As the primate grows and becomes even more difficult to handle, the belt or chain is never expanded. We have seen some terrible injuries resulting from tethering. All injuries sustained are treated and healed during rehabilitation. Sadly, many primates die in captivity as the tightness of their tether means their bowels cannot pass food, enduring a slow and painful death.
