I wish I had the answer, because my bunny has always been a carpet chewer, but lately, it’s gotten worse. She has been spayed for years, so it’s not hormonal. I tried digging boxes, and she just eats the shredded paper I put in there, so I had to take it away. Just this week, I made her an activity box … a big empty cardboard box with toys hanging on the sides that she could chew, tug on, etc. It distracted her for about 20 minutes, and then it was right back to the carpet. If I close the door to the room she’s infatuated with, she will then chew the carpet by the door to try and tunnel in.
Our carpet needs to be replaced anyway, but if it didn’t, this would be an even bigger problem! I’m going shopping for new floors soon, and I’m opting for hard wood. And you’re right about the tiles … if I cover one spot, she either moves on to another spot, or she will keep chewing around the tile to try and get to her chosen areas. It’s a constant problem. Some days, it makes me regret allowing her to be free range.
One thing I noticed lately, is she tends to do it more when she’s lonely. She is an only bun, so on days where she is relentless about it, I will try to hang out in an area of the house that she has access to, and often times, she is then content to play with the toys in the room I am in. Otherwise, it’s off to my daughter’s room (who is in college, and isn’t around), to chew the carpet. I’ve strongly considered getting another bun, but I’m not only concerned about the bonding process, I’m very concerned that the second bun would be a chewer too!
I sure wish I could help you! If you find a solution, please share!
