Stable vices are stereotypies of equines, especially horses. They usually develop as a result of being confined, particularly with insufficient exercise (i.e. in a stable). Vices can develop out of boredom or hunger, excess energy, isolation. They present a management issue, not only leading to facility damage from chewing, kicking, and repetitive motion, but also lead to health consequences for the animal if not addressed. They also may raise animal welfare concerns.
Stereotypical behaviors in animals generally are thought to be caused ultimately by artificial environments that do not allow animals to satisfy their normal behavioral needs. Rather than refer to the behavior as abnormal, it has been suggested that it be described as "behavior indicative of an abnormal environment."
It was once thought that stable vices may be learned by observing other horses who already have the habit, but studies on the topic to date have failed to establish this as a cause. Stereotypies are correlated with altered behavioral response selection in the basal ganglia. Although a more enriched environment may help minimize or eliminate some behaviors, once established, it is sometimes impossible to eliminate due to alterations in the brain.

Famous quotes containing the words stable and/or vices:
“My whole working philosophy is that the only stable happiness for mankind is that it shall live married in blessed union to woman-kind—intimacy, physical and psychical between a man and his wife. I wish to add that my state of bliss is by no means perfect.”
—D.H. (David Herbert)
“Power corrupts ... when the weak band together in order to ruin the strong, but not before. The will to power ... far from being a characteristic of the strong, is, like envy and greed, among the vices of the weak, and possibly even their most dangerous one.”
—Hannah Arendt (1906–1975)
