The Bajang was briefly mentioned in this article about vampire cats. The Bajang is a Malaysian demon cat! This vampire is often described as appearing in the form of a polecat, which is more like a weasel than an adorable, cuddly kitten. This weasel-like, cat-like creature will mew at the door of its intended victims, giving a warning of its attack. This is generally a sign that a child in that house will die; the Bajang vampires especially like to feed on children, although these are not their only victims. The Bajang vampires, like many vampires, can also spread madness and disease among humans.
Bajang vampires are generally male, though not always, and they can be born as Bajangs from the souls of the dead depending on their deeds in life, or they can even be created by a living person. A person can be transformed into a Bajang after death if they have committed evil deeds in life. A person may also inherit the destiny of becoming a Bajang after death. If a person’s ancestors committed evil deeds, they may have passed on, and that person has a high probability of becoming a Bajang vampire after death.
Bajang vampires can also be created by a living person, and used to kill or torment others. The way to create a Bajang is by the summoning the soul of a stillborn child, and in most of the myths surrounding this vampire, the stillborn must be freshly buried, or must be caught before it is even buried. If this restless spirit is successfully summoned, the one who summoned it can control who it attacks or torments.
This is a disturbing vampire, who feeds on children, or may even be controlled by the twisted whims of a living person who was demented enough to steal the soul of a stillborn child.
