Ewok's Vet Bills

Almost a month ago I got Ewok neutered. About a week after, he started having urinary issues. He received treatment and seemed to be doing fine. Wednesday, his problems came back and after spending a lot of time at the vet and having an ultrasound done of his bladder, they decided there was no emergency and to keep an eye on him. About 12 hours later, he became blocked. Our vet could not put a catheter in him because they would be gone over the weekend which meant we had to go to the emergency hospital to have it done. He was severely blocked and had to have about $1800 worth of work done. If he gets blocked while in recovery, it can be more expensive. I'm not asking for the full amount of money. They don't do payment plans and I have no other options. Anything would help.  Thank you very much!
