If you still use postage stamps, I would encourage you purchase
these Animal Rescue stamps.
Because Shelter Pets Deserve a First-Class Meal
In celebration of the new Animal Rescue: Adopt a Shelter Pet stamps, the
Postal Service, together with Ellen DeGeneres and Halo: Purely for
Pets, is giving shelter pets around the country a First-Class Meal.
During the launch of the stamps, Halo will be donating a million meals
to animal shelters around the country.
