We love the cozy caves, but… We are on our 3rd or 4th cave now and the issues with them needing replacing are all around the opening and the hood pipe. Either the stitching comes undone or the pipe digs it’s way through the material, creating so many holes that it is impossible to keep the pipe inside the tunnel. We were probably pushing the tube back in around 20 times a day at the end of our last one, (i.e. every time we walked past). We have now bought a replacement cover. i just wish snoozer would re-design the ends of the tubes, maybe seal them with something round. otherwise, my dogs absolutely love their cave. We've had them for several years now and would buy another one, despite its issues.
