I let me bunnies roam my (small) apartment cage-free. It presents an interesting new set of issues that no bunny book covers. High points: My first bunny potty trained herself. Yoshi didn't see the cage as "punishment" so, after she realized she was free to come and go, she decided where she wanted to.. go. Low points: I have a new bunny, Amelie. Both unneutered females (one 6 months, the other a year and 9), fairly dominant, same size-ish (or will be), neither aggressive (though Yoshi is territorial over me still). Consequently they are both running around marking, which completely undid Yoshi's potty training. Though I will say, they get CLOSE to the cage 99% of the time (the exception being when one has decided that they want a corner to themselves, which doesn't sit well with the other). Does anyone else let their bunnies roam?
