GET THEM OFF THE CEDAR. Cedar bedding causes respiratory disease, liver and kidney failure. Cedar is also a major skin irritant and I can't imagine what those babies are going through being on it. Have you ever stuck your face in a bag of it? It burns your nostrils and eyes immediately. It is used in dog beds to kill insects for a reason. IT KILLS.
GET THEM OFF IT! At least use kiln dried pine, preferably aspen.
