Scunci's end of life medical care for oral cancer.

My name is Nancy Tipton. I am the CatMom  to my beloved 15 year old Maine Coon Cat mix Scunci. Scunci lost one of his canine teeth 3 weeks ago, nothing unusual for a cat his age. But, several days ago I noticed that he had quit grooming himself and made little cries whenever he yawned. So I looked into his mouth and noticed a blackened red spot where the tooth had fallen out. From seeing these before, I realize there's a strong chance that Scunci has early oral cancer. I reached out to Companion Pet veterinary clinic, they referred me to a lower cost clinic that only requires $28 for the diagnostic and the first 20% of the treatment plan upfront, with the other 4 installments monthly. He has his Diagnostic appointment this Sunday August 23rd. The problem is, I'm living on SSI exclusively, and Scunci is my Companion Animal and best friend. This was so unexpected and I was caught off guard and unprepared to afford the veterinary care necessary to save my sweet baby's life. Please help Scunci to get the care he so urgently needs. Any help you can give will be appreciated more than you can ever imagine! Thank you so much and God bless you for helping Scunci.
