I have a JW holder but it didn't work for my guy either! He kept falling off it. So, I got a steak knife and with the tip of the knife made a round hole near the top of the cuttlebone. I used some bird safe string or you could possibly use a plastic C clip to hang it up. Primitive, I know, but it worked. And, then I found out he doesn't even like cuttlebones! The stinker! He just liked climbing on the holder! lol
