Sorry this is so morbid, but Kelly made me think of this new topic!
Apparently in the Bible it says that animals do not go to heaven. I believe the Bible; I'm not saying that. I just can't accept that all those fluffy, loving, loyal pets just disappear when they die. (When they seemingly have the same life-driving presence in them as we do).
I like to think that animals, when they die are recycled into the next generation - always staying on earth. (Maybe a dog becomes a dog again or a polar bear). Whereas we humans come in and out of this world.
