Harvest Moon: A Wonderful Life is a video game that was released in Japan on September 2003 and March 2004 in North America for the GameCube.

The player starts the game with one cow, and can later acquire additional, higher-quality cattle as well as sheep, chickens, and a horse. The cow will stop producing milk after 40 days, and will have to be impregnated for her to continue making milk. In addition to these traditional Harvest Moon animals, this is the first game in the series to feature ducks and a goat.

The player starts the game with a dog, and has the choice of floppy or pointed ears. Later in the game, the player may receive a cat from Romana. Seen in the wilderness are a tanuki, a lizard, and a turtle, as well as a chihuahua that appears to be a pet at the dig site.
