Support Jourdyn's Cat Bullet in ICU

Hi, my name is Jourdyn. I am the owner of two sweet cats, Bullet and Cookie. Bullet had a urinary blockage this weekend. He was brought to the emergency vet and was sent home the same day. He was immediately blocked up again and back to the emergency vet. He is now in the cat ICU with more complications and needs to stay longer. I have put everything I have into healing him, and I have nothing left. The only other option would be to euthanize, which is something I can't imagine. Please, if you're able, help my little angel. Thank you for your time.
