Although jazz bassist Charles Mingus was best known for his musical accomplishments, he was a renaissance man with interests in surprising areas, namely the Charles Mingus Cat Toilet Training Program.
Mingus writes that it took him three or four weeks to toilet train his own cat, and that he wasn’t able to train it to flush consistently – if you want to learn how, you can get the details at his website: http://mingusmingusmingus.com/mingus/cat-traning-program. I don’t have a cat, and I doubt my pet chickens are trainable, but let me know how you get on.
Of course, Mingus is notable for many things aside from cat toilet training. He released landmark jazz albums like Mingus Ah Um and The Black Saint and the Sinner Lady, and supported other luminaries like Louis Armstrong and Charlie Parker. The story of his death is also memorable; on 5 January 1979, he died at the age on 56 in Mexico, and was cremated the next day. On the same day, 56 sperm whales were beached on the Mexican coastline, and were removed by fire.
