Once an egg has been incubated and hatched, it will have a happiness meter underneath it's picture in the basket. This starts at five, but can be increased up to ten by giving other eggs to the pet. Additionally, pets lose one happiness point every twelve hours. A pet that reaches zero happiness runs away. Fortunately, friends can help feed pets by first selecting Give to Friend, then clicking the link under the friend box.
