As far as handling goes, its luck of the draw with any hamster. I had a very sweet dwarf when I was about 10 years old. It loved to be handled. Handling before you buy is the best way to find a nice one. Don't settle for a feisty one if its all you can find at the moment, you'll be much happier if you wait for a friendly one.

The cage bars should be under 1cm or about .45 inches apart. I don't know how you'd keep anything in a cage with 1 inch bars. I hope this was a typo.

The care is the same as the other hamster varieties.
