PetVille adds a sharing star

Just a week old and Zynga's latest addiction, PetVille, is already going through some design changes. When logging into the game today, players will find that a new yellow star icon that lets you notify your neighbor when you've groomed them or gained a Good Housekeeping bonus by cleaning their home. Adding an option to notify neighbors of your actions may be an experiment with allowing players to opt into notifying players, and less of the automated updates that usually occur with other social games on Facebook.
