After all, baby birds need simulated nests, baby opossums should be given simulated pouches, and virtually all other kinds of wild animals will have similar needs specific to their natural histories. Many shelters assess animals and house them in the same room. Because dogs would often be placed in the cages at night, this wasn't the ideal arrangement, but it was the only room available. Many shelters modify a storage closet or other small room for the purpose of wildlife care and housing. Make sure the wildlife area is kept quiet and darkened so that wild animals can feel as safe as possible when being evaluated, monitored, and housed temporarily.
Essential supplies range from gloves of various thicknesses to wire cages.
Be sure to have various enclosures set up and ready to house incoming critters. Properly vented boxes, crates, stainless steel cages, and aquariums with fastened tops all make appropriate housing, depending on the age, size, and species of animal. One of the most essential ingredients in successful wild-animal housing is a source of heat. As Spas says, next to silence and darkness, warmth is the most important need of wild animals suffering from the stress of temporary captivity. The heating pad is a staple of the wildlife rehabber, although many shelters also use infra-red heat lamps and incubators from time to time.
