Hi Sandra,
As you're dealing with a chronic illness, homeopathy would be by far the best approach, but not do it yourself. There's not a remedy to take the place of an antibiotic, there's a remedy for the state of your cat's health. And that will change over time.
Homeopathy for anything chronic should only be in the context of a professional homeopath's guidance over a period of time. How long? For a 15 year old cat who's had heart disease since he was three, it'd be for the rest of his life.
