One of the negatives to having a free running rabbit is Thumper's tendency to chew things that we'd rather they not. Cords, baseboards and furniture are all on the menu.

Bunnies are "hardwired" to chew and therefore cannot help themselves. Since they have open rooted teeth that continually grow, they must chew and gnaw on various materials to wear them down.

You have a couple of options in dealing with this behavior.

First, you should provide them with approved chew toys. Bunnies love cardboard boxes, toilet paper spools, phone books and bunny safe wicker baskets, twigs and sticks. Properly prepared pine cones can also be provided. This is probably the single most important thing you can do. I think that bunnies resort to chewing the furniture when they lack alternatives.

Second, you can restrict their access to things you don't want chewed. You can close doors, put up baby gates and cover electrical cords in plastic tubing or spiral wrap. Some people even make creative use of plexiglass and/or wood strips to protect baseboards and furniture legs.

Chewing is a fact of life when living with a rabbit. With some gentle redirection and training, you can eliminate the worst of it.
