Hi! I have two 10.5 year-old house rabbits. They are caged much of the time now (due to increasing age and changes in my family) but for most of their lives they were uncaged. So, I got used MEGA bunny-proofing. I have yet to find a taste deterrent that works, but plastic cable wraps (spiral wraps that people use to gather or hide their cables) work great. You can find them at a place like Home Depot. Good luck!
