An individual's approach to which philosophy is practiced may depend on the species of animal. Many Americans utilize animal products in their diets and by-products in their lifestyle, but require some assurance that these animals were raised and processed under humane production practices and conditions. Typically, the animal is reported to be emaciated in body condition but is otherwise healthy. Lack of attention to disease and injury can also constitute neglect. In some areas depending on local ordinances and regulations, lack of appropriate shelter or housing also can be considered neglect.
Abuse is the active participation in the physical maltreatment of the animal.
Cruelty centers on psychological mistreatment which inflicts suffering and grief. These types of activities are more difficult to identify because it may depend on the animal's background, training, handling, age, species, gender, or previous experience. Frightening or teasing an animal may be termed cruel. Each component may be deep-rooted in a single issue. Science has a great potential to offer objective, factual information which may truly be the only element that assesses or evaluates the welfare of the individual animal.
