I am working on a project and I am in need of some foul smelling chemicals.  I am looking for a variety of smells.  Urine, Trash, Old beer, Feces, Cat Urine I think you get the idea.  I am looking for a way to recreate these scents in a safe manner.  Preferably something that is hypo-allergenic.  I am hoping to find someone that can make these scents for me and possibly on a regular basis.  Thank you for your help in advance.

Basically we have no idea if you don't plan some idiotic prank, so we can't help much. But there are lots of foul smelling chemicals - scatol, hydrogen sulfide, mercaptans, butyric acid... Probably searching forums will give more.

H2S is very toxic. Lets not. Butyric Acid smells awful, but is hard to get for a prank.
