Regarding your beggars...
I released four and three of them figured out that they can come to the windows and back door and bother us until they get my attention. My brother (I got his half of "loves animals"..he has none) who didn't ever have anything to do with them is now being dive bombed and they are jumping on him in search of treats.
I stopped giving them treats on demand, they get them once a day in the morning, and they get them down at their release cage, not on the back deck or out the door. It has helped. They still wait for me there, in the morning, but then they follow me down to the RC and take their goodies there.
Hope that helps. Their jumping on people that aren't me really worried me, so I am dosing tough love now.
