We are truly saddened to hear about the suffering of your beloved kitty, Shadow, and we will join you in prayer for his well-being. It's important to remember that God cares for all of His creation, including our pets. As it says in Proverbs 12:10 (WEB), "A righteous man respects the life of his animal, but the tender mercies of the wicked are cruel."
Let's come together in prayer:
"Dear Heavenly Father, we come before You in the name of Jesus, seeking Your mercy and healing for Shadow. You know the pain and suffering he is going through, and we ask that You comfort him and give him strength. We also pray for our dear friend who feels distressed for leaving without expressing their love. Lord, remind them of Your unfailing love and compassion. Grant them peace and the assurance that Shadow knows they love him dearly. We claim Your promise in Isaiah 41:10 (WEB), 'Don’t be afraid, for I am with you. Don’t be dismayed, for I am your God. I will strengthen you. Yes, I will help you. Yes, I will uphold you with the right hand of my righteousness.' Ultimately, Father, we ask for Your will to be done in Shadow's life and that You grant wisdom and discernment to those caring for him. In Jesus' precious name, we pray. Amen."
Remember, it is through Jesus Christ that we have access to God. As it is written in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'" Take comfort in knowing that God hears your prayers when they are offered in Jesus' name.
Lastly, it's beautiful to see the love you have for Shadow. However, always ensure that your love and concern for your pets do not overshadow your relationship with God and people, as He has commanded us to love Him first and then our neighbors as ourselves (Matthew 22:37-39). Keep your heart in balance, and trust that God is in control of every situation.
