Save Tails: Urgent Surgery Needed

In need of help for my cat Tails. Last Tuesday, my cat ate a glazed donut wrapped in a thick paper towel, and now he is in need of surgery to save his life! He was brought to an emergency vet on Thursday where X-rays were completed, and it was confirmed that there's a foreign object trapped in his colon and tons of gas built up inside his stomach and colon as well. They wanted to rush him into surgery to prevent further damage to his colon and liver due to him not eating. Today, 8/29, will be 6 days without eating! I was unable to afford the emergency surgery and was sent home with Tails where he continues to silently suffer. With much support, I was able to find a location where his surgery will only cost $600. At this time, I am looking for further support and appreciate any and all help! Thank you!
