I have a group of 3 (2 bucks and a doe) that free ranges my whole flat and I don't really have many issues. All of the flooring is either laminate or lino and they have no problems, though I have put a runner (is that what they're called? A long rug!) in the hall way and there's a rug in the living room so they don't go speeding through and end up injuring themselves (been there, done that, with a dog. £1,300 and a PTS case later, never ever again.) The rest of the place is lino and they have no trouble getting traction on that, even the super fluffy-footed giant. I don't have much furniture they could get under, just the sofa and my bed. The sofa has hardboard trim just underneath it to they can't get in there, and my bed now has a bunch of storage boxes underneath. That's more because I don't want them getting stuck as opposed to I won't be able to catch them, though. All I have to do is slam the fridge door and they dart into the kitchen waiting for veggies. :rollseyes The only problem I have is being woken up at stupid hours of the morning by a rabbit trying to shuffle under the duvet for snuggles!!
