Aww that's great, yeah actually I've been really lucky.. I had my bunnies since they were babies and always had them out so they got used to their surroundings & no never chewed my furniture apart from a window sill. I would defo recommend covering up any wires.. And being honest I don't know what others will say, but I've always found out that rabbits want to get into the spaces you want to keep them out of! For instance, I have floor length curtains, never touched, but when I wedged my shoe behind our sofa to prevent them going down the back, they would do anything to dig their way down the tight squeeze & chew my shoe! Lol! But as soon as I removed the shoe & they knew it was open again, ran down a couple of times & then they didn't bother ever again!
Rabbit proofing can include covering them up or using puppy panels, all depends on the lay out of your room & what your bunnies are like? Have they ever had interest in carpet? Or corners etc? I personally believe if they have lots of toys like tunnels etc they don't get bored. I think it's when they are bored they get destructive.
With my bunnies, every time I saw them trying to squeeze so where or looking like they were going to chew, I would either clap my hands or touch them on the bum & they soon learnt. Bunnies are very clever little animals & soon learn things very quickly!
At night, mine had the run of the house, & I never heard a peep.. They would always settle down the only downside was come sunrise they would be in the bedroom running around as they wanted their breakfast! Lol! Xx
