In multiple cases, the abuser tends to hurt people in their families as well as their pets. They may threaten to kill or hurt their pet if a child or spouse says they will leave the abuser. This causes fear for the animal's life, and the person being abuse tends to stay in the home. In other cases, abusers let their anger out on their pets, or if they had traumatic experiences done to them, the abuser will repeat what was done to their pet.
Laws on animal abuse tend to be relaxed and not taken as seriously. This allows many animals abusers to get away with little no punishment for their awful crime. Some charities are working to fix these laws and make them more serious.
