Where can i buy parts for a c&c cage for guinea pigs (and advice on bedding)?

I don't know about the cages, If you have petsmart they have a website, and you can by stuff from them online or in the store. I'm from canada, so i don't know if you have petsmart, but the link is at the bottom. but you should only use Aspen wood shavings. All the other shavings have fumes that are harmful to your Guinea pig. You probably shouldn't use dust, they can and will inhale it, this is not good. I have heard carefresh is good, but it is manmade so i think it may have chemicals. Do NOT buy a bedding called Fluff, it is made of cotton and your hamster can get tangled in it, it also has lots of chemicals. So your G. pig can make a soft bed, you can through some unscented toliet paper in their cage. Hope this was helpful!
