The Postal Service has released Pets, 20 stamps that showcase the nation’s favorite domestic animals.

The stamps feature two dogs, two cats, two birds, two fish, four reptiles, five rodents, a crustacean, a rabbit, and a horse.

USPS reported in a news release that more than half of all homes in the United States have pets.

“The most common are cats and dogs, but all types of pets provide love, happiness, and companionship for their owners,” said Chief Marketing and Sales Officer James Cochrane, who dedicated the stamps Aug. 2 at a pet retailers’ show in Las Vegas.

“The bonds we create with animals improve our physical and emotional well-being, and our pets truly become family members.”

The stamps feature photographs of animals taken against white backgrounds by Eric Isselée.

Other participants in the dedication ceremony included James Bilbray, chairman of the USPS Board of Governors; Doug Poindexter, president of the World Pet Association; Robert Vetere, founder and chairman of the Pet Leadership Council; and comedian and homeless pets advocate Gregory Popovich.
