They do not like being in water typically. I agree with everyone else, not the greatest advice from your vet. Order some Pam, it is supposed to be the best. Reptile basics also carries a Reptile relief that is supposed to work. The only reason you should soak your snake is every few days with a drop of dawn, to provide your snake relief until the Pam arrives. Soakng is not good for them. Make sure you follow the directions on the pam. Good luck on your battle.
