We just got a Dutch, probably 8 weeks old and tiny! S/he (pet store peeps couldn't be 100% sure) has a NIC cube cage and we'd like to let him/her out for exercise. Would a big pen (like an XL pen) be big enough if s/he's out for several hours a day and then back in the cage at night to sleep? Our former bunny had full run of the living room and ended up chewing carpet and couches and I'd rather not have a repeat of that. We don't have space to create a really big area for the bunny to be in, but I thought we could open up the pen while s/he runs around, then fold it up at night. The NIC cage is really a three-story condo, but until s/he's bigger, we've kept it contained to one level. Thoughts?
