I had a beagle that used to hose my vinyl regularly. Oddly enough, he only seemed to aim at the Led Zepplin albums. It never made them sound better, though I'm not sure it made them sound much worse either. I guess I should have made him wizz on the turntable...... He also peed on my niece once. THAT was quality entertainment.
Inexpensive tweak
Just got back from a business trip to find that our cat had thrown up on my Audible Illusions preamp (unfortunately vented on top). Everything was dried up. Haven't looked inside yet. Not sure how to clean a circuit board. But I've noticed that my system is more revealing than before. I won't share details of exactly where on the preamp my cat got sick because I might want to try to market this tweak sometime in the future. :-)
