Help my baby Emo the cat

My name is Andrew. My roommate and I are the happy cat parents of two beautiful adult cats. Recently my cat Emo has had a medical emergency and tested positive for congestive heart failure/disease and possibly cancer. The medical bills are rather expensive and her mom has several medical issues leaving her unable to work. I am looking for any assistance I can get to help save my cat and provide the best treatment and medicine I can for her. Any help would be greatly appreciated. She is my little angel and I would do anything for her. We are trying to do everything for our cat to give her the best help she can. Even if her life has been shortened we want to be able to spend as much time caring for as we can.
