Bruce's Perineal Urethrostomy

Bruce is my 2.5 year old rescue cat who suffers from chronic urinary problems. Despite receiving a special diet, medications, supplements, and specialist medical care, he continues to get life-threatening urinary blockages.
On October 5th Bruce started screaming in pain, so I rushed him to the vet, where they put him under and released the blockage. Since I'm already doing everything I can to manage the problem, the vet said that Bruce will need Perineal Urethrostomy to prevent further blockages.
I raised Bruce since he was an orphaned 2-week-old baby and he means the world to me. I'm constantly worried about him, and it breaks my heart that he's suffering.
Even though funds are tight right now, I'll do whatever is necessary for him to get better.  I really appreciate any help you can give so Bruce can get the surgery he desperately needs.
Thanks ❤❤❤
