I would suggest sticking it in the freezer (mild chill so it won't freeze to ice), or in the fridge. Keep it in a sealed, tight container like a tupperware and then wrap it in more plastic. The sooner you use that urine, the better the results of your urine or the other person's urine. Source(s):

The Wolf-Bred Twins. Romulus was the legendary founder of Rome, the sons of Mars by Rhea Silvia, daughter of Numitor, King Alba Longa. He was exposed in the wild at birth with his twin brother Remus, By his great-uncle Amulis, who had usurped the throne. The twins were suckled by a wolf and brought up by a peasant named Faustulus, and his wife Acca Larentia. Romulus founded Rome in 753 B.C. but quarrelled with Remus, whom he slew.
