The present application relates to the technical field of pet products, and discloses a remote control device for a pet, comprising a main body. The main body comprises a container device used to contain pet food or running water, a feeding switch used to open or shield an output port of the container device, a control circuit, an SIM card slot, and a communication module used to identify a communication signal of an SIM card. During use of the remote control device for a pet, pet food or water can be placed in the container device in advance, and an SIM card can be purchased and inserted into the SIM card slot. When a pet needs to be fed, a user can use a communication apparatus, such as a mobile phone and a telephone, to dial the telecommunication number of the inserted SIM card of the remote control device for a pet, the communication module identifies, upon establishment of the connection, a communication signal of the SIM card, and then an instruction is issued and transmitted to the control circuit, such that a specific amount of pet food or water is outputted from the container device for the pet to consume. Throughout a feeding process, a user can remotely complete operations by means of an apparatus, such as a mobile phone and a telephone, thus eliminating the need to be physically present at the feeding location.
