Cattle Rippers are a type of boggart known by spooks to feed on the blood of living beings. A boggart that feeds on livestock or animals is called a cattle ripper. These are often bound but can be reasoned with. Eventually a ripper will develop a taste for human blood. They usually trap their victims somewhere where they can't escape, and slowly drain them. The boggart will take a small amount of blood over a period of days, but will eventually lose control and gorge themselves. They enjoy the taste of human blood, and will continue to kill again and again until they are dealt with. Rippers are a type of boggart, that if given the taste of human blood, will kill any human to feed its thirst, such as the case of Billy Bradley.
