My cat Butters is in dire need of Dental Surgery

Hi all, this is my last resort as I really have no other option. My cat butters, has been suffering from eye infections, and unable to eat lately. I took him to the vet, and found out he has lesions in his mouth and bad gum disease and gingivitis. I was quoted $680 for the dental work and cannot pay for that myself with my financial situation. Any help would be appreciated, as my only other option is to get him put down, and I really do not want to lose my fur baby. After paying for his eye infection treatments, I am truly struggling. Thank you to anyone who is able to donate

If anyone can donate, it would be greatly appreciated. ☺️
