Sofa, So Good

Just a couple of days ago we were saying how Mabel and Dijon were behaving themselves since being allowed in 'our' half of the living room... well, they must have heard us and decided that would not do... since then they have been naughty, naughty, and doubly naughty... we have an old piano stool next to our sofa, and they have decided their latest mission is to go under it and burrow their way behind the sofa, using teeth and claws to remove anything in their path.

I'm struggling with this one - every defense I put in place is rapidly destroyed, and it's meant they cannot spend as much time out as they require constant supervision. They know it's naughty, and flick their tails at us if we come near to move them. I'm sure previous bunnies leave their invisible bunny signs to say 'hey, come this way, there's a great tunnel behind the sofa if you can just get there', as it's always been a problem area. Just hope they get bored of trying soon.
