Please help my fur baby

So if anyone knows me even just a little knows my love for animals especially cats ‍⬛. Loui aka  Lucifer (his name if from the Netflix show) but he was acting funny last week brought him to the vet they said it was UTI gave him antibiotics though it did the trick until tonight he was in excruciating pain so we decided to bring him to the animal emergency room and I was afraid that I would be right it’s a urinary blockage and he has to be there for 36 hours until Friday to be transferred to my vet they said it can be risky and I’m just praying everything will go smoothly his vet visit for just the emergency room is $1800 I don’t know what my vet will charge on Friday but if you could please help or just even share it would mean so much to me and my fur baby I hate to even do this but Lucifer is the most Affectionate cat I have ever had and it sounds weird but he is my little soulmate he likes to be carried everywhere and always buy my side! please anything helps thank you so much for anyone who takes the time to read,share or donate!  If you feel better about donating directly to the animal emergency room please PM me I will give you the info!
