 International trade usually causes a high mortality rate during transit , between 30 % and 90 % . Slow lorises also experience many health problems due to both local and international trade . In order to give the impression that the primates are tame and appropriate pets for children , to protect people from their potentially toxic bite , or to deceive buyers into thinking the animal is a baby , animal dealers either pull the front teeth with pliers or wire cutters or they cut them off with nail cutters . This results in severe bleeding , which sometimes causes shock or death . Dental infection is common and is fatal in 90 % of cases . Without their teeth , the animals can no longer fend for themselves in the wild , and must remain in captivity for life . The slow lorises found in animal markets are usually underweight and malnourished , and have had their fur dyed , which complicates species identification at rescue centers . As many as 95 % of the slow lorises rescued from the markets die of dental infection or improper care .
