Please Help Georgie

Hi, this is Georgie! He’s a 10 year old, (not totally) hairless cat, who’s been our best friend since he was only weeks old. My sister got him as a companion for her oldest son to grow up with when he was only around 9 months old, and her younger son carries him around like he’s his baby. Georgie is an integral part of our family. He’s been a huge source of our happiness since then, always jumping into your lap or crawling under the blankets to snuggle with you and steal your warmth, or ready to bat little paper balls around the house! He’ll even chase you on just his back legs when he’s feeling goofy enough. Unfortunately last week, he went to the vet for some routine bloodwork and a check up in order to schedule a dental surgery later on, and during a routine cysto, he ended up with a ginormous blood clot in his bladder. My sister already tapped out her resources the next day when she had to transfer him to an emergency vet after his blood pressure and body temperature were practically unreadable, where they preformed blood transfusions on him, and there was hope the clot would break up and shrink on its own. But now it’s formed a blockage and she’s left with two choices - try to come up with the money to hospitalize him again, or have to put him down.. we aren’t ready to lose another member of our family, we truly feel it’s not his time, and would like to ask anyone who has the means to, if they could donate to his care. We truly appreciate anything, please keep georgie in your thoughts and prayers. He’s really one of the sweetest cats, what he lacks in fur he makes up for in personality and love and devotion. He’s been a blessing getting us through so many hard times in the last 10 years, and we want to get him through his hard times now.. thank you all so much
