I fully believe that NO ONE, not even the bible, can answer this question....unless one of us here is god? That is, if there is one. And, as far as I know, none of us here can truly know the nature of god, if there is one. It would surely be mightily arrogant if we thought we could.
If there is not a god, then none of us goes anywhere. If there is one, then surely all good creatures are loved in equality - otherwise, what kind of god, god forbid, would THAT be?
If there is a heaven, I cannot fathom animals not being there as I find them FAR more honorable than human beings. Just my humble opinion.
