I've heard that when someone or the enemy is trying to hurt you and you are a child of God it will attack your pets instead of you. Get closer to God and read Psalm 91 for a prayer of protection also read the bible to get closer to God, cover yourself with the blood of Jesus, and continue praying, for God likes us to talk to him. This way there is communication between him and us.
Lord please protect this child of your and whatever is trying to attack them through their pets send it back to the pit of hell for it never to show its face again. Have that poor innocent pet come back home well and safe soon. Keep your protection over this child of yours, their pets, and home. In the mighty name of Jesus I pray. Amen!
