How can I tell if cats in my neighborhood are unowned or are someone's pets?

There is no definitive way to know except to ask your neighbors. Some have found that posting found signs in the neighborhood is a good way of asking all neighbors at once. If no one responds to your signs, one can assume that while the cat may have been someone's pet at some point, that individual is no longer assuming responsibility and the animal is now unowned.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
