“A righteous man cares for the needs of his animals” (Prov 12:10). God holds us accountable how we treat them, as part of His creation. The responsibility and discipline of looking after pets teaches children valuable lessons and instills positive character qualities. Through interaction pets also provide companionship, amusement, and unconditional love. Sometimes they are taken to hospitals and nursing homes to bring comfort and joy to people in need. While we express love to our pets, we should love people more. There is no indication in the Bible of animals being in heaven.
