Help With Loki's Vet Costs

On April 2nd, my cat Loki was acting unlike himself and I noticed he was unable to use the bathroom when he would go to the litter box. I took him to the vet where they confirmed he had a blockage in his urinary tract that required immediate surgery and a three day emergency room stay to monitor his vitals and make sure he wouldn't re block. Thankfully he is back home and feeling much better, but now we are facing enormous vet bills. Anything is appreciated!
