Misting will help to stimulate the snake to drink on its own once they learn. Soaking the snake may be required to maintain good health, it is certainly a quick solution for dehydration, shedding problems and regular defecation. Defecation should occur at least once every 90 days for adult animals. If it cannot be stimulated by misting be sure to soak the animal. Typically this soaking needs to last from 1 to 6 hours.
Juveniles tend to defecate more frequently.
Adults should be fed once every 30 to 40 days, unless proportions of the viper dictate a temporary variation. Juveniles may feed every 14 days, but be sure to monitor defecation, with 3 feedings for every defecation as a minimum. One of the tricks used to elicit a feeding response in a tempramental Tropidolaemus wagleri is to irritate, or anger, the snake by using long tweezers or forceps and tapping the snake on the tail with a mouse, and then the snout if needed. Manipulation of the snake can also anger it enough to strike. If a strike occurs with a fickle feeder, stay still, or exit the animals field of vision.
