I lucked out, or rather Simba did. I sent on his Petfinder notice to just a handful of people, but one of those friends made a connection with a family who wanted Simba.
I actually drove to Wisconsin with my friend to get Simba, so I got to meet his former family who was heartbroken to give him up. Then I got to meet his new family that was so thrilled to have him.
He is getting along well, although the resident cat still has some reservations. Happy ending for Simba and his former family is glad to know he has a good home and that they can get updates.
A little effort can save a life.
