Hi everyone, I was looking to see if anyone had any input on where I can get non bleached paper bedding? I ordered some from chewy and from small pet select, which I am happy with but for how big my guineas cage is I have to buy 3 or 4 bags and it's expensive per bag :/ I got a bundle off of small pet select of food, hay and bedding which was a great deal for all of that but the bedding was just a small bag. I was in the process of shredding up a bunch of cardboard to make bedding for them but then I read about all the crazy chemicals in cardboard so I just wasted my time shredding all of that up
I really don't want to switch back to Wood because of how much dust it puts in the air for them..
So any kind of input would be greatly appreciated
