I have the Crane teardrop model, which works beautifully, and I hooked up PVC piping directly to the nozzle and up to two cages so the fog goes right into the back of the cages directly. My boys like to sit in the fog when it's warm and I've noticed they shed much faster since adding their humidifier. I have it on a timer so it comes on for 30 minutes every hour or so during the day. They like it!
