I was toying with the idea of using a tranquilizer in the shipping water but, I think I'm going to just go all natural. This is the product I was considering, which lasts 48 hours. But I think that it's probably overkill so I'm only mentioning it for people who like to browse things. http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=12271
