I wanted to do an interesting but informative post, so I looked up some animal facts, and I actually found something quite interesting, though some people may not really think it is true.
Hamsters can be taught to come to you by their name - like a dog.
The idea of your hamster coming to your name seems weird, because a hamster isn't really the sort of animal who you call by name. (if you know what I mean)
But I think its true, because when I leave Lolly running around the house in her exercise ball and I come and find her, if I see her a few meters away from me and call "Lolly!" She usually starts heading my way.
Picture from google images, not actually Lolly
