Help me save Amos’ life

THANK YOU EVERYONE! IM HAPPY TO ANNOUNCE HE DOESNT HAVE TUMORS ON HIS BLADDER (tho his bladder is still not working properly) AND HIS KIDNEYS STARTED WORKING AGAIN! HE WILL STILL NEED SOME TREATMENT BUT I THINK THE AMOUNT OF MONEY GATHERED WILL BE ENOUGH TO PAY ALL EXPENCES! THANK YOU THANK YOU THANK YOU!

Amos is a beautiful 5 year old Maine Coon I got almost 3 years ago. So far he's been my best companion and stress reliever. He's the most kind, patient and well behaved cat I've ever seen. He's never destroyed anything and was never aggressive even if I bothered him.

Last Saturday he started walking weirdly and it seemed that he couldn't poop so I thought it's just that he needs laxative paste to help him poop better.

So I bought the paste and gave it to him but next day he still seemed like he couldn't poop so I gave him a little bit more and waited till next day. On Monday he stopped eating and I got really worried so I rushed to the vet. I thought the vet is going to help him but in the end this one particular vet just made him worse. He didn't even check properly what's wrong with him and gave him some meds, shots and on top of that really expensive food.

Next day I rushed to another clinic and what I got to know is that my cat is dying. He had a temperature of 34°C and couldn't even lift his head up. The clinic told me it was a problem with his bladder, he couldn't pee.

The vet had to push his tummy to help him, and we could see a lot of blood coming out. 80% of his kidneys were also not functioning. From this day on I have to go to the clinic every day and drop him off in the morning so the vet can make him pee, give him meds, shots and ensure his temperature is going up and then pick him back up after I come back from university. He can't control his peeing, so it's just dripping everywhere. Today I woke up to a bloody bathroom floor, when I was picking him up the vet noticed that there was something on his bladder that might be a tumor.

I'm a university student and don't earn much money. Daily visits to the clinic already made me borrow a lot of money from my friend. I'm asking you to help me because he is so precious to me, he is like my own child and I don't want him to suffer anymore, so please please help me get Amos treated and feel better as soon as possible.
