You betcha! There has to be pets in heaven. Try Romans 8:22 or many other places where God reclaims all of his "creations". How about Revelation? Many references to animals in heaven. Even says Jesus comes riding on a white horse or why would a lion lie down with a lamb?. The bible was written for man and his fall from grace. We're the ones who screwed up, not them. The animals didn't have a choice. I know many animals with more unconditional love and kindness in their hearts than many people I know.
