Socks, like Ruby, is both a sibling and terror to Scourge. Preferring to play with his sister, this cat constantly belittled Scourge throughout his kithood; when he is abandoned by his housefolk as an adult, his fate is left in the paws of Scourge himself.

Socks does not have many lines, particularly as an adult; although his character holds significance in the story, there is little to record on his behalf. His voice actor must be able to produce both a child and adult rendition of his voice comfortably, but the audition will be judged mostly concerning how his younger voice sounds.
