Haha, the only time it drives me mad is the odd occassion when one of them gets spooked and thumps into the night... normally just when I've just got into bed. Thankfully doesn't happen so much any more. They seem to have chilled out a bit.
I have the black (paint?) coated one with a metal floor, which I have covered with carpet. They don't chew it but then they have lots of other things to chew and neither are really 'chewers' anyway (unlike Miss Sylvia Bunny who will chew anything as long as it causes relatively expensive and highly inconvenient damage...) b-m
