Fluffy is SO adorable! I think that instead of keeping him in a cage they should let him go out FREE! Would you want to stay in a cage almost all your life? I know I wouldn't so why should we make him?!
This is a god and bad idea. The good thing is people can get to places quicker and the bad thing is that they could kill animals on accident because the animals can't see the train because it's "Invisible"
