We want more Americans to know about the millions of shelter pets that need good homes. Nearly half of the animals that enter animal shelters are euthanized. Many of these cats and dogs would have made a wonderful pet...if only given the chance.

You can make a difference. Adopt a pet, volunteer at a shelter, or just get the word out by buying these stamps.

The Stamps

This campaign continues the Postal Service's 50+ year tradition of raising awareness of serious social issues with special commemorative stamps. The 44-cent stamps feature photos of five cats and five dogs who were all adopted from shelters.
