I am sorry to hear of your recent losses.
Pure winter whites are hard to come by sara!
We are currently looking for a sapphire pearl mate for our sapphire who is a young hamster with quite a few show wins now. We may have some pups if we can get her mated. We are in Holmfirth.
There may some for sale at some of the shows like Emly in August or if you look on the Northern Hamster Club site at the shows I could try and find out if anyone has aby available and let you know. They are few and far between at the moment and most breeders keep them close for fear of any hybrid breeding into the pure lines.
You can see Harriet our female on

We do currently have a litter of baby syrians born Monday if they were of interest?
