Worms

My friend Lisa went to a workshop this weekend and I am babysitting her silkworms.  The little sweeties are shedding and they don't eat when they shed, they eat 24 hours a day, then they stop, freeze in their tracks until they crawl out of their skin and start eating again. This process can take days, and they can die during this phase.  She couldn't plan her workshop around her worms shedding?
