Is it normal for his voice to change? It's higher pitched now... I think the humidity is just too high and he thinks it rains all the time. I did some research and it said that they do it after it rains, so I might just regulate the fogger to 75-80% and use my Hydrotherm... It was difficult to set up and I dont know where to put the sensor... I have it at the top corner away from the fogger... I don'd really have anywhere else to put their home, I think he will just have to drown it out, it only lasts for like 30 seconds...
