URGENT PLEASE HELP -

I need help paying for emergency vet bills and comfort care for my cat. His lungs and chest cavity are full of so much fluid it's putting pressure on his heart, and he is gasping with every breath. We don't know where the fluid is coming from, but none of the possible explanations are curable. He is drowning in his own lungs.

My kitty, my baby, I've had for 13 years, is dying.

I'm making this GoFundMe because of the bills it cost just to find out that little information. We still do not know why or where the fluid is coming from.

The only options I have are to drain the fluid and just wait and see how long it takes to fill back up (because it will fill back up), or euthanasia. I just need help, please.

I live on my own and my rent is due the first week of August, and this has just eaten all of my savings. I Start my sophomore year of college on August 23rd and that tuition is another $3,000 with $525 due in the first week, not counting books and supplies. I'm studying forensic biology.
