- I dissent.
Cedar is considered unsafe due to the phenols (same with pine, to some degree). If you haven't read the GL page on beddings, you might find this useful:
Some owners have used wood pellets with some degree of success. I believe they do use a layer of fleece on top. I currently use paper bedding, and it is by far my preferred choice.
There is no such thing as a perfect system for dealing with the bottom of your pig's cage. The last few years I had pigs, I used fleece and towels. It requires you to clean more often, but each cleaning was relatively quick and easy and there is less dust and less mess around the outside of the cage. Less dust was important to me because I am allergic to dust and also have asthma. The downside, of course, was that I had to launder the pig's bedding on a regular basis. (PS: I used wood stove pellets in hay bins and loved the absorbency and how it kept down odors.)
I had a sick pig who had very strong smelling pee. I figured out that by putting the pine pellets (sold for horse bedding or feline pine for cats) really keeps smell to zero. I now just use it in the corners they pee in, rather than the whole bottom (whole bottom of cage does indeed make for a LOT of heavy clean up). I feel they are too "unstable" (they shift around, not sure how this would work for a horse!) to use as an "only" bedding, so I put the aspen over the top.
I recently got a pretty large cage w/2 additional piggies. We added a balcony to almost double floor space and I am trying the fleece up there to see how that goes.
So, if you decide to give this a try, you can purchase these items much cheaper if you have a Tractor Supply near you. Their cost of litter is by far the best, and they have some nice hay, but I do not like any of their foods, so have to go elsewhere for that. We have 22 total critters and have to go all over town to get all their supplies!
