Last year, we had two that got stuck in the garage for about a month. I thought they would have died without water, but when we finally found them, they were just fine and I returned them to the outside. Currently we have one that hangs out beneath the gutters of the house near the roof vents for the greenhouse. He starts croaking whenever it begins to rain and it is really quite loud. You can coax him into "talking" with almost any crude imitation.
