Sebastian and his younger brother Sam were the first lemurs to become residents of EPF's Prosimian Sanctuary. Both were born into the pet trade in south Florida and purchased by the same family (at different times), who kept them until they became unmanageable and began attacking people. Sebastian had significant social skill challenges when he arrived, likely related to being hand-reared and socially isolated during his developmental years. Although he continues to require special attention with regard to social interaction with others, he has found several Ring-tailed lemur companions at the sanctuary who tolerate his social skill deficits well. He and his brother Sam are no longer very compatible, so they live in different groups most of the time but can see each other from a distance.
Hormone changes from being neutered cause Sebastian to look more like a female than a male Red-fronted lemur. This happens in dimorphic species (where males and females look different).
Sebastian's 2019 care expenses are 100% covered by his generous sponsors, Tracy and Paul Fenn.
