Help Goliath: life saving surgery

Goliath is a 12 year old Maine Coon kitty. Super sweet with the look of an old soul. This mellow kitty has been on a roller coaster of urinary blockages, repeated catheterizations and a bout of sepsis after bladder surgery to remove a jagged struvite stone. All of this in the last 2 weeks. As you can imagine, the bills are mounting up and have passed $2000
already, and now we have gotten word that they want Goliath to go to a specialist for PU surgery. This is not a surgery we would choose for Goliath, but have been told it would be life saving for him. I can't stress what a sweet, loving fantastic companion he is. This campaign is to try to raise the funds necessary for the specialist. I have already absorbed the bills for a week of hospitalization at his vet's, a weekend at the emergency clinic for his infection, and will have more bills after the catheter is reinserted today. If you can find it in your heart to donate, you'll be giving my Goliath a chance to live. As a self employed musician I feel despondent that I can't come up with the $5000 plus needed to save him, but my funds are gone. Even a small donation can help him live. Thank you so much
