My 2 Russian dwarfs are girls, and are named Pip and Squeak. They aren't very old or big and I got them on Thanksgiving this year.
Previously, I've had 3 hamsters since 3rd grade and they've all been teddy bear hamsters-very sweet!
I hang lettuce around the cage using large clips and it makes my hamsters more active because they smell the food and try various ways to reach it. It also keeps them occupied. Rotating the toys in the cage also keeps them interested and plastic tubes provide them a sense of freedom as they can crawl through them on contained "journeys".
We can keep talking on this site since others may want to share these ideas.
