Bruce's Emergency Vet Bills

Bruce is just under 2 years old. He is already had quite a rough start, his mother and siblings both died from panleukopenia. He's a survivor. 
Now he has a severe build up of crystals in his bladder. He is unable to pass them, or urinate which has caused his kidneys to begin shutting down.  He needs surgery to remove the stones from his bladder. 
He has been in intensive care for 2 days, and he isn't improving as expected. Bruce needs to continue treatment to improve his kidneys, so he can get the surgery asap. If he has the surgery, he'll be able to live normal with a slight risk of crystals coming back, but with a new diet and close watch things won't get this bad again.
Vets at Blue Pearl Animal hospital have been wonderful, but they require payment in full before the procedure. I have already spent $3,300 on his care, and they know my situation so they're trying to help me find other places to have the surgery at a lower cost. $5,500 was the high end estimate, and the low being $4,200. Anything can help.
I am asking for help now because I've extended as much as I can to care for him, and I'm not ready to say goodbye.
