Help Spazzy get his ultrasound

My friends cat Spaz has recently been diagnosed with acute renal failure. He recently went into remission after fighting diabetes for years,  then got the news shorty after that his kidneys were failing. He is only 10 years old, he should still have many years ahead of him. My friend has been paying several hundred dollars a month for the past couple years, for all the bloodwork, his insulin and now for his new food, subcutaneous fluids and medication to try and help his kidneys. He will also require more follow up bloodwork. Ultimately he will need an ultrasound to determine if his kidneys can be saved. Ultrasounds are quite expensive and during this difficult covid time, money is very tight. She has 2 other cats that she has to care for too. Anything will help, thank you guys so much, let’s save Spaz!
