i just went and smelled mine. no, it does not smell like cat piss. it doesn't really have any smell. maybe a faint hint of a drywall or chalk scent, but definately not cat piss. ick.
DAMN i bet that's what killed my @!&$%*! babies, i am surprised they grew at all!!!!!!!!!! thanks for the quick response (that's funny you went to smell yours LOL)
you know it never even occured to me that there was something wrong with it, i smelled it and thought, uh well, maybe it is supposed to smell like that??? THEN everything that i have planted using it has started to die, lost 3 Master Kush ladies and i am praying the bagseed make it through, they seem to be much hardier. i changed soil, etc and was gonna mix a new batch for some more MK and i thought this ain't right, sure as shit, the bag says odorless and the internet says odorless so i thought i would ask my friends and YOU say odorless, so i got some shitty perlite, MFers owe me 3 MK beans
