Safe woods for rabbits to chew on include:
1. Apple
2. Willow
3. Pear
4. Birch
5. Pine (in moderation and only if untreated)
6. Maple
7. Ash
Make sure that any wood you provide is untreated, free from pesticides or chemicals, and sourced from a safe environment. Also, monitor your rabbit while they chew to ensure they don't ingest large pieces that could cause digestive issues.
