Thats such a sad loss for you, to see Mouse suffer like that, that tears the heart right out of a Pet Guardian to see thier Fur or Feather Companion suffer, and to know that theres in some cases nothing that can be done about it.
Our All Mighty Lord God in his infinite wisdom and nercy has made our Animal Companions immortal as he has done with the best among us, and has created a world where they can be with us in spirit and travel together all around the world , enjoying all the places they in most cases would have not gotten to see in life.
And where they can be there to greet us when its our turn to join them in Paradise , as Mouse Angel is now searching for just that right place , where you can be together gain, and enjoy life in Paradise forever.
One Fine Day.
