Pet rabbits will chew your stuff. Really they will. People ask me, "How do you keep him from chewing your wires?" Well here is my answer: I move my wires.Rabbits need to chew daily to keep their teeth from growing too long. That may be why your rabbit chews things like your baseboards. Maybe. But it is not usually why your rabbit chews wires.
Rabbits plan their escape routes in advance. When you see a wild bunny zigzagging through a meadow into the briars, that is not random. In an absolute emergency they may go off course, but normally the escape has been practiced and planned. They run the course daily clipping any vines or briars out of the way so they have a clear, rabbit sized path, to move through swiftly when being chased.
(See he just had to move that Lego house!)
Your sweet indoor bun is simply clearing his escape routes when he clips your wires. Usually rabbits like to plan sneaky escapes, so squeezing behind the couch is a favorite path of many pet rabbits. People often have wires behind their furniture to "hide" the wires. You can see the rabbit's only option is to clip those intrusive "vines".
My rabbit Bramley used to keep the couch "clean", as it was one of his escape routes. He would take my daughters books and toys and toss them like a Frisbee (from his mouth) onto the floor. Once the entire couch was clear he would flop down and relax.
(Legos everywhere!)
Moral of the story: Your rabbit will plan an escape route (or 2 or 3). You can learn what his plan is by watching how he hops through the house. Then you won't put anything you don't want chewed in his path. (Sometimes rabbits even decide your couch is in the way.)
I know it would be nice if I could just "tell" the rabbit not to chew. And sometimes that works or at least helps, but going against their nature is very difficult. Moving your stuff is generally easier.
