As soon as our animal companions cross over the rainbow bridge, they are in the light. They are free of whatever physical illness or limitations (if any) they may have had. At this point they are perfect, but those of us left behind, their human parents/companions and other animal family members are the ones still suffering.
Generally what they want to convey is that they are okay. They are better than okay. They often share visual images of themselves looking perfectly happy and healthy. For example, if they had trouble walking in life, they may show me that they are running, leaping even!
Many animals try to find a way to reassure their loved ones left behind. They may appear/visit in dreams, or in spirit. You may see a glimpse out of the corner of your eye or simply sense them. I had what I thought of as a "waking dream" shortly after Jarvis crossed. It was the middle of the night, and I had gone to the restroom and he was sitting on my bathroom counter, as he had often done in life. I felt like he was totally ok, and I think I petted him. It felt so real and I call it a waking dream because it felt dream like in the sense that I did not think it was strange at all.
He also found ways to leave me messages that would remind me of him. The photo to the (top)left is a sticker I saw at the grocery store tea aisle. it said "Jarvis" on a green strip next to a number. It had nothing to do with the tea or any products near it. I smiled, took the photo and bought the tea! The cardamom pu-erh is now my favorite! The photo below (left) is a book that arrived in the mail as a gift when I was experiencing stomach pain the summer after he crossed. I smiled again when I noticed it was written by a doctor with the last name Jarvis. The apple cider vinegar did help me tremendously :)
After Juneau crossed, as I mentioned in a previous post, I kept seeing hummingbirds drinking very deeply from their feeders, the way he would drink water & that made me think of him. I also saw a black cat in our backyard that I had never seen before or again since that day. I am still not sure if it was a visiting "real" cat or spirit cat. He was just lounging on the hill, very calm & relaxed.
Of course when the grief is fresh, sometimes these signs/messages bring tears to our eyes, and our animal companions may refrain because they don't want to make us (more) sad. Eventually, after time passes, thoughts of them bring smiles too (or smiles & tears at the same time.) I am so grateful that I can still connect with Jarvis and Juneau and "talk" with them often. They have taught me that the love we share with our animal family members continues after they cross over and it truly is forever.
