What makes urine smell like rotten eggs?
Urine is the garbage disposal system of the body. If you’ve processed it, used it and don’t want it anymore, it goes out the pee-pee. That’s what happens to Sulphurous compounds that you don’t want anymore… they get used, processed and dumped into the toilet, outhouse or bush, or whatever works for you. Rotten Egg smell is H2S, or hydrogen sulphide. That’s the similarity.
