SCOTT #4451-60 ADOPT A SHELTER PET 44 CENT

    In 2010 the U.S. recognized a major problem with abandoned pets in the country. Trying to make the citizens more aware of the problem that exists, the Post Office printed the "Adopt a Shelter Pet"  souvenir sheet featuring 5 different dogs and 5 different cats. These sheets created a rush to shelters to adopt a pet. Everyone has to do their share TO RESCUE A PET.
