Hey,
If there is a problem with wrinkly scales, I would remove the water box, and in its place, place a wet towel, a couple of days prior to shedding. However, these scales should get back to normal with the following shed cycle. I don't place pans for soaking in the larger blood cages, but do place a large damp towel in the cage when the animals are known to begin the shed upon inspection. Either the day of shedding or the day before.
