Going back in our very long human history there are probably more instances where a person held a rat like in the pic above than where a person was using a mouse like below. Therefore holding a rat is more natural. As a former owner of a pet rat, but also a modern computer user, my usage ratio of rat/mouse is probably something like 5/95 at this point while skewing towards the situation pictured below.
