I know Cedar is a no because of the smell causing respiratory issues but alot of things I saw was people saying anything pine is toxic. But I also saw pine shavings are the go to for brooders which is what confuses me lol. I personally would prefer to get Aspen. Cause I've done alot of research on it when I was in a gerbil addiction phase lol But if pine is usually safe then it's really up to what my mother wants to pay since im just manual labor and research XD. And I asked about paper because she was curious and is planning on getting a shredder for paper and cardboard to add to the brooder.
