OMG how adorable!
I had one of these little lovelies a while back.
I worked in a pet shop and always ended up bringing home all the little oddities that couldn't be sold.
This particular little hamster had had one ear bitten off by her siblings.
At the time they were called Russian Dwarf Hamsters, so my dad used to call her Ivan Earoff.
Her real name was Button. And she was adorable.
