Maltreatment of animals for entertainment
In addition to the exploitation of animals in cruel sports, zoos, menageries and circuses are increasing in number as more people with few qualifications enter the business of displaying exotic animals. Animals may be confined for long periods in small cages. They may have untreated wounds, exhibit neurotic symptoms, or be chained. Animals ranging from mice to dogs may be fed alive to carnivores. The animals may be improperly fed, mixed with others when they are naturally solitary, or deprived of any means of distraction (in the case of primates in particular).
