Wyoming amended its cruelty law in early 2011 to include the new offense of "household pet animal cruelty." Under the general anti-cruelty part of the law, a person commits cruelty to animals if he or she knowingly and with intent to cause death, injury or undue suffering overrides an animal or drives an animal when overloaded, unnecessarily or cruelly beats, tortures, torments, injures, mutilates or attempts to kill an animal, or carries an animal in a manner that poses undue risk of injury or death. The neglect component provides that person who has charge and custody of any animal and unnecessarily fails to provide it with the proper food, drink or protection from the weather, or cruelly abandons the animal, or fails to provide the animal with appropriate medical care is also guilty of cruelty.
