My daughter kept going on about these hamsters, and after searching everywhere, finally got one in stock at Amazon. The hamster runs about, stops, changes direction, all the time making noises as he runs. My daughter finds this hilarious and keeps her happy for ages. When she picks it up, she presses his head and he goes into cuddle mode, whereby he stops moving and starts making noises every few minutes.
The cats find it amusing as well, using it as practice for their nightly mouse hunt outside. All am waiting for now is the house and bed to become available at Amazon.
