Alexandra Cabbot has a Tuxedo cat named Sebastian. Sebastian is the reincarnation of a witchcraft-practicing ancestor of the Cabot family, Sebastian Cabot. Alexandra finds that, by holding her cat in her arms, she can cast powerful magic spells (Alexandra and Sebastian’s bond is represented in that they both have a matching white stripe in the middle of their hair/fur). However, this plot device is used very rarely, and Alexandra has also been shown to be able to cast spells without Sebastian being around.
