My step-sister, Mary, had a black cat named Sheba back around '80/81. Don't know where she got the name from and she actually never had anything to do with the cat, that I ever noticed... And I am quite certain she had no knowledge of COME BACK LITTLE SHEBA. She wasn't terribly bright...but, none of my step-siblings were.
It was a nice cat but it was never allowed to come indoors, and it had kittens constantly.* I could never convince my father and stepmother to get the poor thing fixed or to let it inside.
*Yes, this was all during my 3 years of living in "white trash" conditions as a teenager in White City, Oregon... still, it was considerably better then the alternative of living with my mother and stepfather.
*Now that I think of it, my stepmother's kids all seemed to reproduce on a regular basis, as well.
