To clarify one thing though. The glitter didn't come from the Asian Leopard Cat that's the wild ancestor in Bengals. It came from a domestic cat that was used in the breeding program so it is something that can happen naturally in domestic cats.
However no other breed is specifically breeding for it and I don't know of it having shown up elsewhere, other than in that one cat that was used when the bengal breed was being developed. That's not saying it can't show up in moggies and people just didn't know what it was.
I went to quite a bit of trouble but managed to capture Nikita's glitter in a photo:
If your cat is showing that sprinkled with dust type sparkle in his fur I guess it'd show up as being like silver or mother of pearl sparkles rather than gold like in the brown cats.
