What kind of hamsters are the easiest to take care of?

None of them are hard to keep, but they are all kind of dumb and boring. If you want a really interesting pet rodent get a rat - seriously. The are sold in most pet stores in a wide variety of colors. They are very friendly and smart. You can even teach them to do tricks! No hamster will ever learn a trick like roll over or fetch. They make MUCH nicer pets than hamsters.
