One of the things I tried to test the hearing of my deaf ferret is a squeak toy. The rest of my busyness goes nuts when I squeak a certain toy, so I figured if Chaos was indeed deaf, he wouldn't be affected by it. He wasn't. He ignored it and the large ring of keys being tossed behind him...as was said before, I had to be careful to do this when his back was to me...Chaos is very quick to pick up on movement and reacts quickly.
