Need to understand: What I am? But more important: What is this? I have four paws and a tail This has two paws and no tail I'm little, but strong This is bigger and taller I like to leak this thing It gives out strange sounds What an unusual situation! But not bad, if I have to say I used to live in a cage It came and brought me away Here, where I'm wondering now I don't know yet, but I like it.
