 As part of the trade , infants are pulled prematurely from their parents , leaving them unable to remove their own urine , feces , and oily skin secretions from their fur . Slow lorises have a special network of blood vessels in their hands and feet , which makes them vulnerable to cuts when pulled from the wire cages they are kept in . Slow lorises are also stress @-@ sensitive and do not do well in captivity . Common health problems seen in pet slow lorises include undernourishment , tooth decay , diabetes , obesity , and kidney failure . Infection , stress , pneumonia , and poor nutrition lead to high death rates among pet lorises . Pet owners also fail to provide proper care because they are usually asleep when the nocturnal pet is awake .
