Cat's Life at Risk, Need Your Help

I'm really embarrassed to do this, but I think we all know that I would be nothing without my cats, and I know how that sounds. My youngest wasn't there when I woke up this morning and he sleeps with me every single night so I knew something was wrong and when I went to find him, picking him up, made him cry. He kept crying on his own, and was walking funny and his brothers wouldn't leave his side. I took him right to the vet, and we discovered that his uretha is blocked. I was only able to afford to make him comfortable and to remove the current urine in his bladder. The vet would like to put a catheter in for 3 days, and the total with blood work comes to $2000, which I do not have. I spent every last cent to do what I could for him this morning. I am ashamed to ask for help, but he's my youngest and my sweetest and my craziest and just look at that nose. I don't know what I would do without him, and I want to at least try to save him. There is a surgery that can prevent it from happening in the future and make the passageway bigger in their urethra, and I can save for that surgery, but I unfortunately find myself at a place right now where financially Im not doing the best and l can not borrow from anywhere so please don't feel obligated but anything would help. And I would send anything back if I don't make enough, but I just want to save my crazy little boy if I can. My four little fur children are my entire world and I need them. Thank you for not judging me.

And if you are unable to help as obviously, I know what it's like, positive vibes sent my way would be much appreciated. Thank you guys. Thank you so much.
