Help for Maxx's surgery which is needed asap

Hi, My name is Jillian and I have an amazing 11 year old cat named Maxx. I am fundraising for a surgery Maxx needs immediately. Maxx has been through several health concerns which have left me without any resources for his surgery. Last year he began experiencing nausea and vomiting which is causes by swelling in the pancreas. He now receives daily prednisolone which has treated this well. Recently calcium stones were found in his bladder. They do not dissipate with the special diet he is on. They require immediate surgery as they are causing pain urinating, bleeding when urinating, bladder and urinary infections and the chance of possible urinary obstruction. We have been to the ER twice this week to treat the infections and were cautioned he needs the surgery now. Recently due to the prednisolone treatment he caught ringworm in his ear where the transdermal steriod is given. I spend every dollar I have on his care but am unable to keep up. I pay for 4 prescriptions and prescription food along with constant ultrasounds, urinary tests, bloodwork and xrays. This surgery will give him 3 to 5 good years. This cat is so amazing and playful even when not well. I am not able to afford this surgery. This surgery has become extremely urgent and is needed immediately. Without it I will lose him and with it he will continue having a great life as he is so amazing sweet and playful. This is why I am asking for help. I have no shame because he is worth it. Thank you for your time.
