Mellow's medical bills

Hi. This is Mellow. He is 9 years old and he has cysts in his livers which the vets believe is the cause of his sudden lack of eating. He has been getting nutrients' infusion (force feeding) every day and the bills have reached up to 2000€ already. With ultrasounds, xrays and other blood tests included.

The bills are expected to rise another 2000€ in the next few days with the insertion of a feeding tube, other imagery and a possible surgery. Any help would be really appreciated!
