i really do think that they can recognise there owner and be friendly to certain people. i dont understand why eople say that they cant. there is no possible way to prove that they cant.
i think that once they know the scent of certain poeple (their owners) they recognise that they are not an enemy. i'm sure that they know that they are locked up in a little cage all day and once there owner takes them out they get to move around and explore. just my opinion
