I recommend cardboard cat scratchers for carpet chewing, and using heavy ceramic tiles to block the “hot spots” that they like to chew the most. I also have had really good success with the “snak shak” log for my most active buns. It lasts a long time because it’s super hard. I usually reserve mine so they can only access it during exercise time, to keep them from chewing my baseboards.

Also I’m not sure of your set up, but if they have carpet in their 24/7 enclosures, you may need to switch out their flooring to something safer, because if they are ingesting carpet it could cause a blockage. I have vinyl flooring in my bunnies’s pens. They have some textured versions at the hardware store that are pretty cheap (about .50 cents a sq foot). If you make sure the edges are outside their pen, they can’t chew on it. Then I put fleece blankets and grass mats on top for a bit of extra traction.

The benefit of the fleece is that it is somewhat safer if it’s accidentally ingested. You could also do cardboard over the vinyl, which would definitely be safe (although not as nice to look at). Maybe you could cover the hot spots with tile, and then put cardboard on top?

The snak shak is technically a treat, but it’s mostly wood, and is super super hard. I get mine the large log shaped one, and it lasts two bunnies several weeks to go through. I usually give them access to it for several hours a day, when they are most active.

The other thing mine love are organic palm plates. I usually give my pairs 2 or 3 a week. They usually eat the whole thing in 12-24 hours.

One other thing, is you can get these cardboard tubes at hardware stores, sold as concrete building forms. Once you peel away the thin plastic lining they safe because they are just cardboard, and my bunnies have all loved them. You can cut little holes in them and stuff them with paper and the buns will work on “expanding” the tunnel system.

Dollar tree as cat scratchers which makes them very affordable

I’m still suggesting phone books… but I know that are pretty much non-existent now.

Ohhhh the other thing my bunnies really like chewing cardboard egg cartons! I’ve heard it’s not hygienic to use ones that have had eggs in them, but you can order clean ones in bulk for cheap!  You can also throw some pellets in them for an enriching toy. 🙂

Oh! You can also get untreated pine planks and attach them to the wall where you baseboards are. Then they can chew on those instead of the baseboards! I think there is some info on that in the “bunny proofing” section  under “rabbit info”. Some buns really like to have something solid and anchored to sink their chompers into.
