You are running an animal shelter. You have 4 rooms for different types of animals. Your goal is to make sure all animals in these rooms are happy and taken care of. You can click on every animal to see its status and perform actions such as feeding the animal, playing with it etc. The rooms must be cleaned every once in a while. If you do your work well, you'll earn money. You'll need it to buy supplies, equipment and decoration.
