This is normal rabbit behavior.

Here is an excellent article from Marinell Harriman one of the founders of the House Rabbit Society that might help explain this:

^^^that was the exact article i was thinking about… altho, is he older than one year? i don’t remember if it was you, or someone else who had an adult, unneutered bunny that was having similar behaviors. some rabbits are just more destructive. that is my Meadow bunny. seh is going to chew and dig our couches until they are a pile of fabric, wood, springs and foam. that’s just her. it sounds like he need to be confined when he cannot be supervised. have you thought of an xpen or a NIC pen/condo? you can make it as large as possible, so that you know he has space, but cannot harm anything. you were right to ditch the too-small hutch, but some bunnies cannot be free-roam.

My rabbit Giselle was destructive up until recently – okay, that’s not fair, she was an extremely busy rabbit who loved to destroy stuff :~)

I have had her for about 5 1/2 years and she came to me full grown but not spayed so I have no idea how old she really is.

I have had to keep her confined due to her busy nature. But this year she has really slowed down.

teenager stage can be anywhere from 3-4 months, usually up to a year. it is very likely that he will continue to mellow, but like Sarita said, it takes time. my Meadow is (counts) approx. 16-17 months also, it would be nice if by next summer she was less destructive… like with Lilo, squirt bottles don’t always work with her. i’ve had to start tossing throw pillows at her (VERY gently, and i don’t actually hit her with them!) to direct her attention away from the couch.

congrats on the pregnancy. have you given any thought to clicker training Lilo? check into it… http://www.clickertraining.com/training/critters/clicker_train_rabbits/?loaditem=rabbit_videos

if you could get some cue words set up that might make things easier further in the pregnancy and after baby comes home. Lilo sounds like a smart guy, he might be bored. clicker training gives them something to use their minds for and they get rewarded. you can also distract from the bad behavior. now would be the time to do this…

It’s wonderful that you’re having a baby.
I agree that setting up more confinement for him now is a good idea. You may find you won’t want him to have free range once the baby is here for a variety of reasons. If you start now he will be used to it before the next major change happens in the household.

And an energetic adult bunny doesn’t seem to slow down or lose their interests for quite a while. Spockie was at least 6 or 7 years old before I noticed any significant mellowing. However, he did seem to finally realize that some things just weren’t tasty snacks and even if he made a passing stab at chewing he’d lose interest and go to something more satisfying. Like my pant leg. LOL.

Also is he bored? Does he have enough to do? I’d give him lots of stuff to chew, and something like the maze haven, and/or some tunnels and cat condos -if he’s busy doing good stuff he might also stop destroying stuff around the house

mygoodness what a handful.
