Re: The ideal bedding
Initially when we got our guinea pigs the previous owners had been using CareFresh (they even brought a partial bag!) so I continued using CareFresh for my boys. Needless to say, it is rather expensive. I then read on some of the boards about wood pellets and that they were very inexpensive. So I bought a couple of bags -- they were only $4.99 for 40 pounds. While they are cheap I found them to be very heavy to deal with. Also, once they are wet by urine then the pellet breaks down and they become sawdust. This is somewhat hard to clean out of the cages even with paper lining the bottom of the cage. Though I do find it is easier if I roll up what I can (the weight of the wet sawdust tears the paper) then scoop out the rest with a dust pan.
Currently I am still using up my last bag of wood pellets and because they don't seem comfortable to walk on or especially for my piggies to lay on, I am putting CareFresh inside of their hide-a-ways so that it is more comfortable for them.
Still, in search of the ideal bedding (comfortable, cheap, easy to clean, etc...) I recently went to a farm supply store and bought 2 bales of kiln dried pine The bales are quite large and were $4.49 each. I haven't opened them yet (still using up the wood pellets) so can't offer any comments about the smell or the texture. I will post here once I open the bales and use it for my piggies and share what I think about using it as bedding.
Hmmm, perhaps while I have the CareFresh, the wood pellets, and the kiln dried pine maybe I should try the experiment which CavySpirit suggested. Oh, yes and I need to be sure to include carpet as one of the choices.
