We can presume, but we do not know for sure if our pets will be with us in heaven, but it seems possible from these verses that might be a possibility. Where else could such a thing happen?
The royal line of David is like a tree that has been cut down; but just as new branches sprout from a stump, so a new king (that is the Christ!) will arise from among David’s descendants.(Isaiah 6:11)
The spirit of the Lord will give him wisdom and the knowledge and skill to rule his people.
He will know the Lord’s will and honor him and find pleasure in obeying him.
He will not judge by appearance or hearsay; he will judge the poor fairly and defend the rights of the helpless. At his command, the people will be punished, and evil persons will die. He will rule his people with justice and integrity.
Wolves and sheep will live together in peace, and leopards will lie down with young goats.
Calves and lion cubs will feed together, and little children will take care of them. Cows and bears will eat together, and their calves and cubs will lie down in peace. Lions will eat straw as cattle do. Even a baby will not be harmed if it plays near a poisonous snake. On Zion, God’s sacred hill, there will be nothing harmful or evil. The land will be as full of knowledge of the Lord as the seas are full of water.(From Isaiah 11:2-9, GNT)
Waiting with anticipation, for Jesus.
