Q. 1. Do pets go to Heaven?
A. 1. Nothing can be found in the teachings, the Tradition, the Bible, the Canon Law and the Catechism of the Catholic Church to support that pets go to Heaven after they die. That includes the birds, the fish, the insects, the flowers, the trees, and all other life found in the universe with the exception of human life.
None of the aforementioned, except human life, has a soul (self-consciousness) that raises it above all living creatures. Animals were created by God and given to man for his use, not abuse.
It is sad when you hear of people who are convinced that they will need the comfort of pets in Heaven. They do not have a clue as to what awaits them in Heaven. The blessed hope that awaits those who are saved shall include eternal bliss, supreme happiness, utter joy or contentment in the eternal presence of God. Such peace and contentment far surpasses whatever comfort a pet can bring to a human being in the physical world.
