Stan, shouldn't the cat really be responsible for cleaning it?
Nah, that's silly... sorry, I don't know what came over me.
Wait for a nice summer's day and hang your Mooradianon on your clothes line (that thing you often see your wife standing
near (Lol!
). Use the garden hose on it and then let it drip dry. Obviously you need to take the bass out before doing this. I think this will work. You could probably have it dried in an industrial dryer... if it shrinks, just give it to a cellist as a birthday present.
Also, tell the cat to pee somewhere else next time.
Also, tell the people in the orchestra what happened to your bag so they won't think you're a guy with a bit of an odour problem.
