Zues heart disease treatment

Hi! Thank you for clicking the link that led you here. Zues has cardiomyopathy otherwise known as heart disease. Essentially he has a heart murmur, blood clots, and weakened heart muscles. It’s been hard for him to breathe, he’s barely been eating, and hasn’t been playing much. He’s been isolating himself a lot. He is on multiple medications and constantly busting the vet to maintain his condition and prevent it from getting worse. If his condition progresses without treatment it will most likely lead to heart failure which would give him only 6-18 months to live. I’ve put so much money into his vet bills as is and I’m struggling to keep up with them. Zues is an absolute angel and I’m terrified to lose him. If your able to help in any way at all PLEASE do. Me and Zues would both greatly appreciate it.
