we have having done our best to 'cat proof' it. and tbh, it melts my heart to watch her. she only goes out there when i am there and i tend to keep a close eye on her although she doesn't seem interested at all in what is going on beyond the fences. The fence at the end is high and either side is netting (from previous owner) covered with very high over grown ivy (old garden). still nervous about her getting out although she doesn't climb/jump,not even indoors really, pretty lazy cat. spends most of her time lying down lazy bugger
