Save a Meow, Save Burger!

My three-year-old Himalayan cat, Burger, is currently suffering from Feline Lower Urinary Track Disorder (FLUTD). FLUTD is a condition that affects the bladder and urethra of cats. Which leads to being unable to urinate. And worse, get their bladder blocked. Burger is currently in critical condition and needs surgery asap. However, I am a student with no money and support from my family, but I still want to save my lil giant eater, Burger. Please help save Burger!
