Thanks, yeah that's exactly what was confusing me!! His ears don't seem totally round, but in some pictures they do look kinda round and they are very small. It doesn't help that he's not very chubby, as I've noticed a lot of these winter white hamsters are very rounded looking lol. But he does have the winter white body shape. I don't think the ears look like campbells ears though because theirs tend to be huge and stick out as far as I know.
Ah well if he's not pure winter white, he's in a very convincing disguise lol.
I saw your thread, it's really good! That's what I was talking about when I said before about it being good to compare a hybrid to a pure breed, as I think that's where people get a bit stuck as when they look kind of like them they assume it's one rather than both.
Anyway I'm rambling on. Thanks for taking a look at him!
