In a legitimate wild animal sanctuary, animal welfare should always be the priority. Animals should be housed in a manner that respects their species-specific needs based on the Five Domains model, and enclosures should be designed in a way that best mimics their natural environment with the opportunity to withdraw from other animals and people (visitors). The premises of the sanctuary and the enclosures within should be well-constructed and regularly maintained to prevent animal injury, animal escape, and unregulated access by the public. Quarantine and isolation procedures should be in place for new and sick or injured animals, to protect the individual animal as well as the population. The sanctuary should not take in more animals than it is equipped for, as overcrowding and lack of resources are detrimental to welfare. The sanctuary should work with experienced veterinarians that regularly assess the animals’ health, and that can carry out routine, preventative, and emergency medical treatment. Sanctuary staff should receive regular training to be able to identify welfare indicators of the species they care for. Direct interaction between humans and animals should be strictly limited to care and trust-building activities by the caretakers. Animals should not be forced to perform unnatural behaviours for entertainment, including feeding demonstrations, feeding of animals by visitors, or any hands-on contact or 'selfie-opportunities'. Ethical euthanasia should be included in the sanctuary’s welfare policies.
