What a lovely setup, I wish I could do something like that with mine but the foxes are rampant round here and are not afraid of coming out during the day if they smell something nice. When I used to put the bunnies out at night sometimes I got a glimpse of two eyes in the torchlight and it sent shivers down my spine.
Mine do something similar now though, they have the whole of upstairs to run around in, excluding the bathroom (chemicals) and my parent's room and they are still usually to be found in their enclosure. :lol:
