The other night one of my male rabbits broke out of its cage by chewing off the zip ties that held a couple cubes together. Unfortunately, my other male rabbit was out playing and they got into a fight but luckily no one was hurt. This event could have been deadly to one of my rabbits since both the males are dominant and male rabbits will fight to the death. I just want to let rabbit owners know that if provoked, per say by a male rabbit, a rabbit can chew through C&C cages put together with zip ties.
