The Bible is very clear that there will be animals in heaven:
Isa 65:25 5 The wolf and the lamb will feed together, and the lion will eat straw like the ox, but dust will be the serpent's food. They will neither harm nor destroy on all my holy mountain," says the LORD. NIV
In Revelation 5:8-13 all creatures recognize Jesus as the Savior of the world and praise God right along with redeemed men.
In Psalm 145:-9-10,13,15-21 God loves all His creation and has made plans for all His children and the lesser creatures to enjoy His eternal Kingdom.
Romans 8:19 says that the lesser creatures await Christ's return to redeem the sons of God so they, too, will be released from physical death to eternal life.
Romans 8:21-22 says "Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God. For we know that the whole creation groaneth and travaileth in pain together until now".
Rev. 19:11 I saw heaven standing open and there before me was a white horse, whose rider is called Faithful and True. Is. 11: 6-8 The wolf will live with the lamb, the leopard will lie down with the goat, and the calf and the lion and the yearling together; and a little child will lead them. The cow will feed with the bear, their young will lie down together, and the lion will eat straw like the ox. The infant will play near the hole of the cobra, and the young child put his hand into the viper's nest. {We believe this refers to the millennium, but could also refer to the new heavens and new earth.}
Zech. 14:20 On that day "Holy to the Lord" will be inscribed on the bells of the horses... Note: The passage from the Revelation shows that presently there are horses in heaven. The passages in Isaiah and Zechariah show that there will be animals in the millennium kingdom on earth. The present violence in the animal world is a result of the curse in the garden of Eden pronounced by God due to man's sin.
Rom. 8:19 -22 The creation {this includes animals} waits in eager expectation for the sons of God to be revealed. For the creation was subjected to frustration, not by its own choice, but by the will of the one who subjected it, in hope that the creation itself will be liberated from its bondage to decay and brought into the glorious freedom of the children of God. We know that the whole creation has been groaning as in the pains of childbirth right up to the present time...
At times you can almost read your animals thoughts as they make decisions about which food to eat, which food not to eat, how to get out of a pen, how to sneak away from you when they know they are in trouble, etc.. From Numbers 22:21-34 {about Balaam and his donkey} it is quite obvious that at times animals are much more spiritual discerning than people are! As for the animals, however, we know that animals do have souls. We know that the soul lives on after the body has died. We know that there are presently animals in heaven. We know that there will be animals upon the earth in the millennium kingdom. We also know that God himself watches over even the birds of the air {Matt. 6:26} and takes care of them. To say that animals don't go to heaven when they die has no foundation in scripture!
Do Animals Have Souls? Most of us have heard all our life that animals do not have souls. Yet the first chapter of Genesis indisputably contradicts that position. The Hebrew word for soul is nephish and refers to the part of our being which lives on after physical death. The first chapter of Genesis not only proves that animals have a soul, but it also proves that plant life does not! Here are the verses: Genesis 1:20 And God said, Let the waters swarm with swarmers {fish} having a living soul and let the birds fly over the earth, on the face of the expanse of the heavens. Genesis 1:21 And God created the great sea animals and the creeping things all having a living soul...
