[Coopdog]

To clarify: The animals are not "sold". They are adopted out by the shelter staff, and the same screening is carried out. That means they are vet checked and treated for any illnesses/infestations by the shelter vet, and dogs/cats are neutered before the adoption. Potential owners are screened for landlord approval, family situation, etc. They also receive a coupon for a free vet check with any of several local vets after adoption.
