Don't feed the animals. If you feed stray cats at your back door, guess what you will get over time, more and more stray cats. I have been working on the homeless problem for decades and believe me. Everyone knows that if you feed wild animals they will lose the ability to feed themselves. It is no different for the human animal. So stop being selfish. Feeding the wild animals may make you feel better about yourself and make you feel like you are a good person. If you want to really be a good person. Contribute to an Organization that transitions people out of homelessness.
I cringe when I see people giving money to panhandlers. People think that panhandlers are poor and down on luck, fact is there is one and only one reason people panhandle, they get money when they do it. If no one gives them money, they stop.
