Mark your calendar! April 30th - NEW USPS SHELTER PET AWARENESS stamp

PEOPLEPets.com The following things are guaranteed to make you feel good about life: Getting a letter in the mail with cute stamps on it, adopting a pet from a shelter, feeding shelter animals. Now, thanks to the U.S. Postal Service, Ellen Degeneres and Halo pet food, you can do all three!

Starting April 30, the USPS will be offering special commemorative stamps around the theme of adopting shelter pets as part of their annual social awareness campaign.

"This is a subject that I am extremely passionate about. By working together, we can find good homes for millions of adoptable, homeless and abandoned pets," DeGeneres said in a press release. "And until they get adopted, I'm happy to say that Halo and I are giving one million meals to shelter pets that are waiting for you."

The 44-cent stamps feature portraits by photographer Sally Anderson-Bruce of five cats and five dogs, all of whom have been adopted.

They include gray kitten Peaches, who was born under a porch; golden retriever Buddy, who was a pet-store puppy with really bad hips; Australian terrier Bindu Su, who now visits a local nursing home every week; and Frankie, a kitten that lost his mother and two kitten siblings, but who's now thriving at his new forever home.

The stamps, in panes of 20, are available for pre-order at stampstotherescue.com.
