Natural bedding gives hamsters a safe, absorbent material to burrow through, with aspen shavings and paper bedding being the go-to safe choices. Crucially, avoid pine and cedar shavings, whose oils can harm a hamster’s airways. The best natural bedding is absorbent, low-dust and holds burrows well. We compared natural hamster beddings on absorbency, dust and safety, so your hamster can burrow deep in a healthy home.
