Hi Tina,
Welcome to the world of Bengals
Ok I think the coloured collars come in kittening packs, I purchased one from ebay that had scissors, aprons, torch etc plus the coloured collars. Maybe that is worth looking at, not sure of where else to suggest. I just call them Boy 1, Girl 1 etc as there is usually a marking that I can tell them apart on.
Thank you for your lovely compliments, think you should post some pics of your little gang!
