Well..thanks all..looking to test the adhesive aspect I tried it on the repair of a concrete leaf.. Edna had made and gave to me on a visit to VA... It has broken a number of times before... For one reason or another... A little shredded fiberglass fibers in the concrete it's self would.have helped this somewhat... Freezing and high heat didn't help.. But the last time it was just sitting where I had left it...sounds like it might be a cat related issue this time
