Support Harvey Dent's Dental Surgery

My name is Autumn and this is my baby cat Harvey Dent. He has had a hard time lately. He has ulcers along the top of his mouth and tongue. This has caused him some serious pain. He has trouble eating and grooming. Unfortunately, the solution is full tooth extraction. We have already dropped almost $400 at the vet. He had some bloodwork done and received a few shots to help him in the meantime. The surgery is estimated at about $900. Needless to say we need help with our guy. He is nine years old and we love him dearly. We would love for him to have as many years as possible. He is already starting to have some pain again and time is of the essence here. I know times are difficult but any help is greatly appreciated.
