Disposition of shelter companion animals from nonhuman animal control officers, citizen finders, and relinquished by caregivers.

Many private not-for-profit humane societies have contracts with their local government entities to provide nonhuman animal control services that the law commonly requires the government to provide to its residents. These services normally have the humane organization providing either the total animal control program (including field work to pick up stray animal companions, enforcing local animal ordinances, and the impounding of stray companion animals) or just the boarding of companion animals with no fieldwork or enforcement duties. Shelter companion animals normally come from three main sources: (a) stray or lost companion animals impounded by animal control field officers or animals impounded for violations of humane care regulations; (b) stray companion animals brought to the shelter by a resident who happens across, and catches, a lost companion animal and delivers the animal to the shelter; and (c) companion animals relinquished by their caregivers.
