An animal injection system under the control of a remote operator. The system may be used to inject animals with medications and/or RFID chips. Food bait is provided in such a manner as to require an animal to expose its chest and underside. Cameras are used to determine the orientation of the animal and its gender. Images of the animal are sent to the remote operator who determines whether or not to inject an animal. Cellphone networks may be used to transmit animal images to the remote operator and send commands from the operator to the injection system. The system may include a temperature control system to maintain medications in a pre-selected temperature range.
