Cat suddenly appears in neighborhood. (Very friendly, evidence it had once been someone's pet)
Lady in neighborhood feeds cat. (mentions maybe that wasn't a good idea)
Second day, talk with a couple of people and decide it should be taken to Human Society.
Third day, didn't see cat.
Fourth day evening, cat gets hit by a car then hides.
Fifth day morning, cat is found crying and dragging its self with hind legs paralyzed.
Call animal control so cat can be put out of it misery.
Note to coward who dropped cat in neighborhood, because of you and your lack of responsibility toward your own pet several people had to be put through pain and sorrow seeing your cat suffer. I shutter to think of the anguish and unrelenting pain that poor cat suffered all night long. The responsible thing for you to have done if you were unable to care for it was take your pet to the Human Society.
