I had pets come back, my long time pet literally jumped bodies apon his death, his soul was in two bodies the last 3 weeks of his life, when he died it was clear to me his spirit was pulled out of his body, keeping some of the story off the board, by the next day he was back in my home as a baby girl, I knew it was him, (I'm leaving a lot out about why and how I knew and the details) He/She became my greatest gift as my baby girl, because she knew me, we were already bonded, she was back stronger, more obnoxious, my best friend. I had four years with her. Her life was taken by someone pretty much on purpose. She was everything to me. She isn't replaceable.
