Dead Cat 1, along with the 4-5 others from the Dead Cat series were sorry little 1ft twigs at the LSU orchard a few years ago. Last time I was there (last summer), some were dead and the others looked pretty sickly. I don't know if there are other clones out there.
Dr. Johnson told the story of sending out a student to take cuttings from some trees in an area set for demolition/construction, and there was a dead cat nearby, so the name was born.
I don't know if they were figs from the original O'Rourke research, or just some figs growing on campus.
