Ways to physically block of areas of your home and furniture to avoid damage and make safe for a house rabbit
One of the best ways to prevent damage from your house rabbit from chewing and digging is to block off areas of your home. Electrical cables should especially be protected as they are vary tempting to bunnies and can be extremely dangerous if they get cut through. Gaps in furniture that can be crawled into should also be blocked off as your bunny could crawl into them and hurt itself trying to escape.

Pet gates
Blocking off doors with pet gates can be a useful way of keeping bunnys out or rooms that you need to access without the problem of having to sneak in and out trying to prevent a breakout. They are easy to deploy and put away and are a lot better in the long run then replacing damaged to doors that your bunny tries to chew its way through to find out what you are up to on the other side.
Using a variety of non destructive sheet material around your home can improve safety and prevent access. Frames made out of wooden boards can be placed under furniture to prevent access to the underside of sofas and chairs. Ceramic tiles can be brought out and laid on the floor to prevent digging and shredding of carpets and Perspex shielding can be used as a discreet way you preventing into areas such as the back of television stands or on walls that have become the focus of unwanted shredding behaviour.

Wire fencing
Most pet stores provide a pet fencing or a pet pen that is made out of sections of tough wire that can be assembled using re-clipable plastic ties. This type of fencing is ideal for deploying to areas of your home that are unsafe or that you which to remain undamaged and can then easily be packed away when not needed. Multiple pens can be broken up and reattached in chains of fencing to block of larger section or single sheets can be used across corners or to block of gaps.
