I love this! Also, I like what another poster said about all animals returning to their creator. That would be SO many animals in heaven! What if every insect that ever lived was there too? That would be absurd! Does that mean only pets go to heaven? Or only mammals?
That's something I've always wondered. I believe that animals do go to Heaven, but their own special Heaven (like Rainbow Bridge). I believe that the animals that is deeply connected to a human, and the human believes in God and Heaven - the animal(s) will be with them. For example - if Jane Goodall has passed on in Earth, and she goes to Heaven (I am just making an assumption that she believes in Heaven) - she will have all the chimps that was with her/that she saved.
I believe the other animals - wild animals, predators, and prey animals that are given to our animals (crickets/mealworms given to Lizards for example), etc, gets recycled in the Earth.
I've had 15 mice once - I took care of them, but I never have a deep love relationship with them. I do not believe that they will be with me in Heaven. My cats and my dog, and even my two bearded dragons, I definitely believe that they will be with me because I have a much deeper relationship with them.
Oddly - I also believe that while they're (the animals) waiting for us, they're still with me in spirit. Once in awhile, I feel like I have more cats on my bed than the physical cats that are sleeping on my bed. I always felt like the cats that has passed away is around me somehow.
I do wonder if our passed on animals' spirit is somehow put in the ones that are alive. My cat, Jamie, passed away a few years ago. I can see some of her personality in my current cat, Telly. They even sort of look alike (brown tabby). She would do a few things that only Jamie did.
Sorry for such a long post!
