My father is a veterinarian and i saw him counsel people on this type of situation through my whole childhood. There is no easy answer. As for me, I have a cat that, if it wasn't for my wife, I wouldn't even spend the money to vaccinate. I had another cat, that suffered from end stage renal failure, and I gave her nightly subcutaneous fluids for 1 1/2 years. She went on vacations with us so i could give her the fluids.
