Amanda,
  You asked for comfort and supporting words concerning seeing your pet again. I would like to refer you to John Wesley's sermon called "The General Deliverance".  Here is an url to a copy of it. http://wesley.nnu.edu/john-wesley/the-sermons-of-john-wesley-1872-edition/sermon-60-the-general-deliverance/. It has helped me a great deal when ever I am confronted with the pain and suffering of animals.
 I trust the Lord Jesus with the comfort of people who are suffering as well.
Remember the Lord Loves all He has created.
Trust in HIm.
Eleanor
