Can hamsters see anything?
Yes they can see something. I think that they can make out details for a couple of inches and beyond that they only seem to see big objects. One of my hamsters was able to follow my hand when I moved it several inches away from his ball. They can watch a human from across the room and will wait until the human is out of sight before running out of the room. But I have also seen hamsters sprint towards a wall or door and not see it in time to stop before hitting it.
