My cat has a heart murmer and the Vet says it's serious and life-threatening. What are my options? - heart murmer more condition_symptoms

My vet says my cat has a heart murmur, and she said it was a 5 on a scale of 6 in terms of severity. I took it for a pet-cardiac ultrasound of the heart. I can not afford to pay for heart surgery on. Cats with a heart murmur can live a normal life, or my cat is intended to result in a slow and painful death?
