I'm a soon-to-be pig owner and I am still wondering about what bedding top use. I want to use these towels (here's the link: (broken link removed) ) because they are so much cheaper compared to the fleece on www.guineapigmarket.com and I want to know that using towels is safe. I would also put a thin layer of Kaytee Clean & Cozy on top of the towels to keep the towels from being soaked with piggie pee. Please tell me, Are towels safe? Thanks!
