My bunnies are free roaming, this is what we did:
-We covered all wires with cord protectors and hid them in tidy boxes and lifted them out the way.
-We put wood and mount board down the sides of the fridge as we had gaps there too.
Other than that, I can’t think of anything else major that we did. Maybe our house was already relatively safe haha! We’re lucky though, neither bun has shown any major interest in chewing the carpet or our wooden furniture.
I think the key is to look at everything as a bunny obstacle and think what you can do to prevent your bunny being naughty or getting hurt. Cover wires, any gaps that they could squeeze into, anything that can cause them harm – cover it, move it. Anything they could knock off and break – move. Basically, the home has to become your bunny’s home lol. Anything they could chew – carpets, curtains, sofa furnishings etc need to be moved.
One more thing – never EVER assume your bunny won’t do something just because you haven’t witnessed him doing it. So if there is something in your home you’re worried isn’t bunny safe, it is crucial you make it bunny safe. Your bun might not be interested in jumping on the sofa and eating the cushions now but he might one day decide that is the most exciting thing in the world lol.
