Ginger's Medical Fund: bladder stones

my cat ginger has a genetic urinary issue that causes bladder stones this is his 3rd surgery and the only way to limit it is by using expensive medicated food that makes him dehydrated and want to constantly drink water! I’m only 24 and live on my own so it’s hard to keep up with the expenses and I don’t have the heart to put him down he is the most loving cat I have ever met and I will do everything I can before even considering that a option. I am struggling to pay his vet bill on top of the food that’s 100$ a month if anyone can help even a few dollars or just share it would mean so much to us thank you !
