My rabbit does that too… I’m hoping his neuter on Saturday will help some with this (fingers crossed). I’m guessing Cinnabun is already fixed though right?
What has helped for me is mainly covering every corner in which he digs with parts of a yellow page book. I split one book up into smaller sections just ten or so pages thick, and place them along the walls in the corners in which Sammy likes to dig and chew. That has helped a lot. Most of the time he doesn’t move them and go for the carpet, but chews on the yellow pages instead.
I used to spray the area with perfume and it would deter him for a few days, but that no longer works and I don’t want him to ‘eat’ a ton of perfume lol Also, I stay pretty much on top of him all the time while he’s out by listening for the tell-tale chewing noise and immediately finding him and saying NO firmly, and moving him away if necessary so he gets the picture. He totally knows what No means, and I think being consistent is what’s most important…
I also think that adding more things for him to chew on seems to help as well. He went about a week and a half without a willow chew ring from his pen (he loves the binkybunny ones) and I really saw his rug chewing spike during that time… it seems to have calmed down a bit now that he has a new ring and more stuff to chew on.
Hope this helps!
