For everyone contemplating free roaming your buns... DO IT.
Over the past 3-4 months I've slowly been increasing my buns unsupervised time while loose in my bunny-proofed bedroom and they've been nothing but absolutely amazing! (Other than a few stray poops and shredded boxes lol) I've never seen my rabbits so happy.
I was pretty nervous to start free roaming in the beginning but after figuring out what works and what doesn't with my specific rabbits,
I wish I would've done it sooner! It is all about trial and error when starting the free roaming process, be prepared for everything but do not be anxious. You definitely need to know your rabbits personality and interests before going in to it but once you do that, you got it!
Thumper is the Mini Lop, he's about 2 and a half years old.
Aurora is the Dutch, she's about 3 and a half years old.
Here's a pic of their set up (I've chosen to leave their pen up so they have a home base') and some of the bunny-proofing I've done!
