the amonia of their piss is one thing but the phenol oils emitted off cedar is off the charts and causes respiratory problems in almost all mammals including rodents.

Ive used it back in the old days before i seen the effects it does to animals. Ive seen dogs drop dead in their kennels whhen cedar is laid out. And i been breeding rodents for good 7 years now and always use pine.

theres guys on here been breeding longer than me with thousands of rats on pine. I pay about 3$ for a 5cu ft bag of pine that expands to 8cu ft. How is that wasting money when that will clean a good 50 cages.

Lets see some pictures of your so called healthy rodents and them kept on cedar. Better yet lets see video and see if we hear any sniffles or sneezes coming from them..
