dont quote me on this but also there are 2 documented feeder types and i believe the second one, the shelter feeder, is the one that came to the U.S. the purrrr owners are very kind and will probably give you information though or at least a date for when they might become more widely available. contact info here https://www.hipurrrr.com/
My plan is something similar to this feed the cats thing - except, a twitch live stream of an fpv water turret in which they can "deter" those unwanted visitors.
