A disaster is typically defined as a situation requiring external assistance, under the (contestable) assumption that the situation must affect people and society to be a disaster. Animals and their habitats are part of society and humans connect with them, so animals and their habitats are part of all disaster-related activities. This straightforward statement has produced divergent theories, policies and practices including challenges to categories, labels and divisions for humans and non-humans. This paper collates many practitioner aspects regarding animals and habitats in disaster-related activities. It assists in understanding and training for situations involving non-humans before, during and after a disaster. Five categories, sometimes overlapping, are provided of (non-human) animals and their habitats affected by disaster-related activities: companion animals, service animals, livelihood animals, captive animals and wildlife and wildland animals. Other aspects emerge about animals and habitats contributing to disasters and to disaster-related activities. Some ethical and practical issues are discussed regarding rights for, responsibilities of and disaster definitions relevant to dealing with animals during disasters.
