Outdoor access for companion cats is a controversial topic. Some have suggested that outdoor access can negatively impact the welfare of companion cats through increased risks of disease and parasites, injury or death due to traffic, predation or ingestion of toxins, and becoming lost. In addition, cats can negatively influence their environments due to the predation of small birds and mammals, and they are sometimes a nuisance to human neighbors. Despite these concerns, recent estimates suggest that many owners still allow their cats outside, likely because it also provides cats with exercise, and allows them to perform natural behaviors, such as hunting, exploring, and climbing. While some suggest that cats need outdoor access, others recommend ways for cats to meet these needs indoors by providing enrichment and properly supervising cats during outdoor access. This review examines the risks and benefits associated with outdoor access for cats, as well as what is currently known about peoples’ practices, knowledge, and attitudes about the provision of outdoor access for cats.
