Will animals and pets go to heaven? (Part 3 of 4)

Apostle John who saw the new heaven and earth did not give any idea to show that animals were there. Animals of different kinds cannot be found in the heaven. There's no biblical proof to suggest that animals would be there.

In Rev. 21:22, he did not even see a structural temple apart from God and the Lamb. But, in Rev. 21:3-4, he saw the tabernacle of God; and men living happily without sorrow and pain. He didn't mention any animal.

And Rev. 22:18-19 cautions against adding words to, or subtracting words from this book of prophecy.
