Proof that there are animals in heaven..

Revelation 19:11-21

11 Now I saw heaven opened, and behold, a white horse. And He who sat on him was called Faithful and True, and in righteousness He judges and makes war. 12 His eyes were like a flame of fire, and on His head were many crowns. He [a]had a name written that no one knew except Himself. 13 He was clothed with a robe dipped in blood, and His name is called The Word of God. 14 And the armies in heaven, clothed in [b]fine linen, white and clean, followed Him on white horses. 15 Now out of His mouth goes a [c]sharp sword, that with it He should strike the nations. And He Himself will rule them with a rod of iron. He Himself treads the winepress of the fierceness and wrath of Almighty God. 16 And He has on His robe and on His thigh a name written:
KING OF KINGS AND
LORD OF LORDS.
