Actually the biggest problem with handling a snake after feeding is that undigested bones or toe nails and teeth can protrude through the stomach lining and produce a septic infection. The danger time for that is between feeding and 72 hours depending on the temp you keep your snakes.We keep ours at 92 degrees on the hot spot and its 72 hours till bones are not dangerous. Light and gentle handling in this period will usually be OK. but it should be avoided if possible.
