As the pets inhabit the shelter, you will be able to decorate the different rooms and customize them to your own style.
To start decorating the shelter, you will need to select the Tasks button at the bottom of the game's main screen. Once you do, you will see the tasks for the day, which may include decorating or maintaining an area of the shelter.
To complete each task, you will need to use a specific number of stars. Once you have decided on one of the options for the space you are going to decorate, you will need to press the "Select" button to save your choice.
In case you later want to change the style of your shelter, you will need to press again on the space you want to modify and hold it, while the options load, to choose the one you want to set.
