Butters needs his eye removed

Hi everyone I am trying to help my friend raise money for her poor kitty Butters. He was diagnosed with a rare tumor behind his eye that could cause his eye to rupture. Because of where it is and how it grew around the back side of his eye, it will require a specialist that is expensive.  Butters is 14 but still so full of life. If he doesn't have this surgery soon and his eye ruptures it won't be good. Any help will help eminsly. Thank you all for your time.
