About a year ago our cats went from free-range to contained. We now have a contained outdoor area for them which I’ve dubbed the “cat terrarium” as it is outside my office window so I get to watch them prowl while I’m working. Photos and design explanation here: http://www.michevan.id.au/content/cat-terrarium/ http://www.michevan.id.au/content/cat-terrarium/ A year later it has worked pretty well. I had to put some more netting along the bottom of the fence when the neighbour moved a garden bed on their side of the fence which opened up a gap they could get through. But apart from that, their escapes have always been via a door left open too long, not via the terrarium. I really need to set up some more toys and stuff for them out there sometime. Any ideas?
