The present application relates to the technical field of pet products, and discloses a motion capturing device for feeding a pet, comprising a main body. The main body comprises a wearable sensing device, 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, and a control circuit. The feeding switch is electrically connected to the control circuit. The sensing device comprises a sensor used to capture a user motion, and a communication module used to establish a wireless connection to the control circuit. During use of the motion capturing device for feeding a pet in the present invention, pet food or water can be placed in the container device in advance, and a motion is inputted as a predetermined motion. When a pet needs to be fed, a user wears the sensing device on the body and performs the predetermined motion, and the sensing device detects the predetermined motion, performs comparison, and then sends an instruction to the control circuit; the control circuit controls the feeding switch to open for a specified duration, such that a specific amount of pet food or water comes out of the container device for the pet to consume.
