Big boy vet fees

I have taken care of a feral cat Big Boy for almost a decade. Last year he had to have an eye removed. Recently the side of his face where the eye was removed has developed two masses. I am going to take him to be evaluated at the vet. I am in a different place financially now that I have two children and my own pets to care for. If anyone is able to help with a donation for his vet care it would be greatly appreciated. He is an awesome feral cat and deserves the very best.
