I would have to disagree with that, as what makes Humans greater than even the angels would be our free will.
If God, or heaven took that free will away, it would not be heaven, and we would not be what God created us to be.
All though the bible, God only asks us to love him. To love him with our free will, and freely worship him by our own choosing.
If he wanted mindless worship, he could have bought a DVD player.
Without hate, love cannot exist, because love can only be love when freely given, anything else is servitude, and will be hated by those forced to "love".
For the new testament followers, love, and faith is all you need to get into heaven, even the biggest assholes in the world, child molesters, Stalin, and Hitler could get in, if they loved god, and freely worshipped him.
Obviously, it is doubtful we will be seeing Stalin, or Hitler, due to their beliefs, and free will choices, but in essence it would be possible if they freely repented, and loved GOD.
Back to to the original topic, of course animals have souls, the bible says so.
