An interactive device for animals is provided that includes a main body, a driving module and a first rotating member. The main body includes an accommodating groove, an opening, and a communicating channel. The driving module is disposed on the main body. The first rotating member is rotatably disposed in the main body and separates the communicating channel and the accommodating groove. When the driving module drives the first rotating member to rotate in a first rotating direction, the first rotating member drives at least one object disposed in the accommodating groove to enter the communicating channel and leave the main body through the opening.
