gizmo has two cages...both are attached with a pvc tube. He has never touched it before, and it's been in his cage for over a year now. But I did notice that there are two little bites out of it so OH NO! now its worrying time! But a few months ago I purchased (I can't remember from who) the large pcv tube covered in fleece that is attached to the cage. So I am going to cover the PVC tube that I have now w/ fleece to make it safer. But I have no idea how. How do you keep the fleece on? Is elmers glue safe? I know you use polar fleece, where can I buy that? Any sugesstions or help!? I'm a bit clueless when it comes to making things lol
