Luke and his brother Han are angora goats, the breed of goat that is used to produce mohair. Out to Pasture Sanctuary took them in after their previous caretaker could not manage the number of goats they had. Luke tends to be a bit more shy than Han, and while not unfriendly with humans, he tends to be a bit flighty in demeanor, often ducking into the small enclosure within the goat area that was originally intended for the sanctuary cats.
