Fwiw, your cat's eye makers are pretty far off in the listings. No offense intended. I'll trust none taken. I'm seeing quite a few other errors in the non-cats. We'll try to help you straighten them out if you post them here. If anyone is mean to you for getting them wrong, please forgive.
For example: this is a Japanese cat's eye -- called Marble King: http://www.ebay.com/itm/Marble-King-Inc-Cats-Eye-Hybrid-/262321634258?hash=item3d13967bd2:g:MIYAAOSwqYBWoAF4
And this is Vitro Tiger Eye -- called an Akro Helmet: http://www.ebay.com/itm/Akro-Agate-Helmet-Marble-/262321776695?hash=item3d1398a837:g:Jh4AAOSwYlJW25Aj
(Also, if you actually have a Helmet, turns out they are Vitros. For a time some thought they were from Akro, but that was a mistake.)
