I did have one bunny, Forrest, that chewed on two particular areas especially. (He inspired much of the tips in the Bunny Proofing Page!). One area he chewed on was on the outside of the bedroom door which he wasn’t allowed in unless I was there — his goal was to dig and chew a hole to get to the other side when the door was closed. I ended up putting sheet vinyl there in the door way, but you can find clear plastic runner type stuff and I would do that instead if I had to do it over again as it’s better looking.
The other place he chewed on “seemed” random, but we were renting an apartment at the time that allowed pets, and so there could have been an old pet scent there that he was trying to eliminate by chewing it out. I did use phonebooks quite a bit while he was out and that helped. But if you think it could be an old scent thing that’s inspiring this you could just try a deep clean.
Jack though picked up where Forrest left off and even with the squirt bottle and “No’s”, Jack learned to be more sneaky. It did deter him though and he knew he wasn’t supposed to do it — and he did chew less, but if you just want to make things easy on yourself and not have to keep an eye on him every single second then that may not be the way to go.
If the other chew distractions don’t work, then maybe while he’s out you could do the same thing as I suggested above — put the clear plastic runner over that spot. Not the prettiest solution I know.
This is, of course, assuming she has particular places to chew. Otherwise, I have to say, phonebooks have always been all of my bunny’s favorites.
