Makes me want to market a snake shampoo. You know like the water "neutralizers" or "shed aids" and all that other junk that you can buy at the pet stores for unbelievably high prices, suprised it's not out there already, right next to the snake leashes. I always thought molting and cage cleaning precluded any need to bathe your snake (except if you have, God forbid, MITES!!ahh Jesus NO!). This may seem appropriate for a snake small enough to have crawling about on your head but try to picture the burm or retic keepers scrubbing away at those beasts (remember the pic with the Thai kid?). Letting the little guy have a swim in some 80 - 90· water in the tub won't hurt him though but I'd skip the soap.
I feel a little light headed... maybe you should drive...
