I understand that you are excited to have the "Animal Sanctuary" on your farm. The Animal Sanctuary is still in its initial phase of release and is slowly being rolled out to a limited amount of players. Slow Rollouts are important in ensuring the game's stability and new features run smoothly. We will be rolling out Animal Sanctuary to all players in the next few weeks.
We will be sure to keep you posted on this page once the Animal Sanctuary feature is available for everyone.
Thank you for your patience.
