@Amrutha, have you talked to your vet? You might call them and tell them your situation and they may have an adoption area or know of someone who recently lost a cat or has expressed interest in getting another one or two.
Good luck with the rescues. And those of us who care and work in the rescue/advocacy community advise NEVER to post on Craigslist, for the reasons you've already found out. Many innocent lives are lost because people do this. We are trying to get Craigslist to stop allowing people to post living beings on the site.
