Happy Hospital invites future doctors to pass their internship in virtual clinic! As you know, laws require safety testing of drugs on animals before they could be marketed. So, the Wooga developers decided to follow this rule and let you practice on cute little doggies, giraffes, hippos, bears and other zoo inhabitants, before you start treating people! In other words, this time you will treat animals. Build the veterinary clinic of your dream, open new treatment rooms and hospital wards, hire the best staff and cure the nice creatures one by one! Their funny diagnoses will not allow you to take the game seriously. Have fun!
