Cat pee does have LBC content

Hi List,

I think I have cat pee in my diff (but not my rear end, but maybe the 
cats.......) it sure does stink.  The question is, how do I know if it is 
conventional or sillycone cat pee and does it matter?

I definitely didn't have cat pee in my gearbox when I ran a rib case but now 
I have a 5 speed I do.
