Hi, just word from researching on the net and everything about pine or cedar bedding. Pine and cedar bedding can be hazardous to your ferrets, or other small animals. There is a natural oil or something in cedar or pine that can cause respitory infections if the animals breath it in. I use to use cedar and pine bedding, and it does help with the smell to a point. I mean if you like the smell of a forest in your home. But, just a word of caution. It can cause respitory infections in ferrets. A sign to know if your ferrets have respitory infection is, they will get a yellowish color spots, or what looks like dried up snot on there nose, and it can block there nasal passages. I have seen this in MANY pet store ferrets, and have alerted the employess there of the problem. The last few batches of ferrets they have had since my complains have seemed to be o.k. They were still using the cedar bedding, but, i guess you cant change everything. Anyways, when i stopped using the cedar and pine, i put down linoluim in the bottom of my ferrets cages, and started using cat litter. I am still searching for a perfect litter though... looking for something dust free, and something they cannot inhale. [Posted in FML issue 3576]
