Is my new hamster a hybrid?

[BettysMum]

Hello hamster friends!

I've just bought a new hamster called Betty. The woman at the pet shop said she's quite big because she's 7 months old and they've been struggling to sell her.

At first glance she looks black but if you look closely, she has little 'tufts' of white hair at the back of her ears and on her bum. When I brush her coat she's has white fur underneath.

The woman at the pet shop said 'hamsters weren't her thing', the other workers clean them out and handle them so she couldn't tell me much about Betty.

From the pictures, would you say she's a long hair/short hair hybrid? I've had short haired Syrians before and Betty's coat appears very different. Or could it be she's gone white from the stress of being kept in a pet shop for so long?

Any help would be appreciated
Many thanks
