Personally, I don't care about gold versions but since there have been some discussion I would like to make proposal that would keep everybody happy.
Basically, if these are vanity versions of pets why not make vanity equipment for them? For example, if you have regular Toor you can buy Gold vanity to make it Gold Toor. Simple solution for people who are willing to put extra money just for appearance and additionally collectors wouldn't have to buy two same pets just to complete stable.
