Great quality product at a great price
The tunnel and den are of good size for my quite large adult cats - they love to chase, hide and nap! Product is made from a nylon material which I prefer to velour-type products which tend to become matted with cat hair. I was initially concerned that the velco which secures den to tunnel might come apart, but this has never happened despite many hours of rough and tumble with 4 adult cats. A great value purchase when compared to more expensive tunnels I've bought in the past.
