You've got to know your enemy and employ some strategy though. Turns out cat shit isn't a hit-and-run weapon but is much more effective in a prolonged, sustained assault.
I was once privy to a domestic altercation where after some sabre rattling, a certain dude proceeded to throw a full box of cat litter/shit/piss down the stairs at a certain woman. This proved to be both a strategic and tactical failure as said dude underestimated his enemy and expended all his resources in a single attack. Upon shaking off the incoming, said woman proceeded to return fire with no less than 24 glass beer bottles in a prolonged, sustained barrage...during which, said dude BECAME a woman, lost his will to fight, accepted unconditional surrender, and we haven't heard a peep out of him since.
Know your enemy. Know both the capabilites and limitations of your weapons systems. Weapons are just tools. They're only as effective as the operator.
