red ring around both irises

Question
I was at a friends house and they had a large white long-haired male cat who has gold/yellow eyes. I notice both eyes had a thin red ring around the irises or the very outer edge of the eyes. My friend hadn't really noticed it. Have you ever seen that and is that common among certain kinds or breed of cats? Just curious, thanks.

Hi Lee

If it had been a blue eyed cat I would have said that it was the way the light was catching it.  However without actually seeing it, it would be difficult to say what it is.  I imagine it would be very difficult to take a picture of as any flash would bleach it out.  If you are able to get a picture in full daylight without a flash, that showed the pink then I could have another go.
