Are pine shavings okay for a rabbit hutch? I heard its bad for them to breathe in....is that true? My rabbit is going to live with the chickens but not on the floor with them(in a hutch). Is it okay if it is breathing in pine shavings because that is what I use for my chickens bedding? Should I use straw in the hutch? Also what should I use as bedding in the litter box?
