How do you revive a dormant snail My friend has a snail that isn't dead but dormant and shes wondering how to revive it?

If a snail is dormant then that is part of its natural cycle, just like some bears hibernate. So you shouldn't revive it. When it is ready to wake up, then it will. If it starts to smell, then it's not dormant and you should add it to your compost bin. If I think something dangerous has happened to mine, I run it under lukewarm water.
