Extra picture of timer and bar multi-outlet is only an example showing the multi-outlet plug connected to the timer which is not included.  This multi-outlet plug adapter bar will allow you to operate two feeders at the very same time from only one timer.  Just plug it into the facial outlet of one of our timers and then plug each feeder's power supply into it.  It will only fit two power supplies.  You could also use the same technique using a Wi-Fi smart plug.  Note:  Style and/or color of multi-outlet plug may vary.
