So my new rat Maia is constantly sneezing. She wasn't at all untill we put her in the cage. Even when she is sleeping, you can hear its hard on her. (She doesn't seem sick at all, and like I said was not sneezing or anything before putting her in the cage)I am currently using Aspen, I haven't had any trouble with Fay or Nova using it.My question is, for those who use care fresh (paper?) bedding. Has anyone ever had any issues using it?I never got it before cause of the price. I also have not used it since i was 13-14 when I had a bunny. I don't remember any experiences with it from then.
