Twig is a tom.
In Firestar's Quest, Twig is Skywatcher's brother, and the son of Lowbranch. He, along with his brother, were trained by Pricklenose, a friend of Lowbranch, in a way similar to the mentoring the Clans have. He does not formally appear, but Skywatcher mentions that when they were young, a Twoleg left out kittypet food for them. Twig ate the Twoleg food and decided it was a lot easier than hunting, and left the loner life to become a kittypet and live with the Twolegs. Skywatcher claims that he never saw his brother again.
