You see, humans only have souls due to Heavenly Father breathing the breath of life into Adam.
But as children of our Heavenly Father, we breath in a bit of our souls into those pets who we have as companions in this earthly incarnation.
We may also know the truth of this by the simple realization that heaven would not be heaven for us without those we love.
And finally, we may know this as cats and dogs are not born with original sin and never fell from grace.
What is that heaven like?
For starters, they go there at once, without needing to wait on any Judgement Day. They are there in waiting until we get to our destination. And if we fail to arrive, then they still remain in their heaven.
But what is the nature of their "pre-heaven", so to speak, until they get to join us in ours?
For cats, it is a place of endless fields of catnip, growing fresh under a warm sun, where the rabbits are all deaf, the mice are all blind, and the birds are all slow and low flying.
Where all laps are warm and inviting, and random bushes grow brightly colored balls of yarn, and at night, little red dots dance and caper under the cool, but not too cool, skies.
As for dogs, they too have a heaven, but my prophetic inspiration only applies to where my pets - all cats - go to.
That's all. You may know this to be true because a God that didn't have it that way would not be the just and merciful God of the Holy Scriptures.
