I hope this doesn’t sound dismissive of others opinions, but I wouldn’t presume to state with certainty that pets will or won’t be in heaven. It would be presumptious to state with definitive language what will occurr. God created all things. If He decides that we need our pets in Heaven, it will be. If not we won’t see them. If a person has a pet that they love and they hope to be reunited with them, I am not sure it helps to dash their hope. We just don’t know. I prefer to believe that God will provide us with all we need, including our pets. I can’t wait to see how it turns out
