"Our Nora is a bit of a biter, and loves to chew apart paper sacks and cardboard boxes. This tunnel has that same satisfying paper-crinkle sound, but none of the shredded paper or board on the carpet afterwards! She was slightly startled by the sound of it when my husband and I uncoiled for the first time, but she quickly got down to leaping into and onto the tunnel and batting about inside it. The material seems very sturdy and claw-resistant, though we've only had the tunnel for a few days. The suggestion another reviewer made to put a toy inside the tunnel has worked out really well, too -- we throw one of her jingle balls in and that's an hours' entertainment. It comes in a nice little nylon pouch for very easy storage. All 3 of us are very pleased with it!"
