Maybe the rat smothered her face before she could cry..that is so gross but they said they could be big. How big would they have to be? She was pretty little, maybe she couldn't get the rat off of her. How long does a death like this take, that poor child.
Ok rats can be as large as small dogs, and can and do a lot of damage in different ways quickly. Perhaps, rather than us telling you horror stories, it would be helpful for you to look up rat information on the internet? It can be and is very, very bad. I am sorry, it is just bad and this baby is not the first to die this way. (The truth is difficult to read, but maybe you can since you have an interest.)
