Back on topic, I have always had the feeling that if a condition can be controlled with minimal intervention from us, then it is worth the time and money. For example, we lost our cat in December. When we took him in at the end of October, we were given several options. The initial visit the vet was able to palpate an enlarged and hardened kidney, but wanted to wait for the results of the bloodwork and urinalysis to offer a diagnosis. At that point, his opinion was that he was suffering from kidney cancer, not just chronic renal failure. We were given some options as far as testing to definitively confirm the diagnosis, along with a few treatment options. We agreed to an xray, but declined an invasive biopsy. We felt that at 15.5, he had lived a great life and if it was in fact cancer, he deserved to be treated well for what ever time he had left. Again, with administering fluids at home, we did it twice, but felt that it was too distressing to him to repeat. We realized that he was at the end of his life, and it was not worth the expense or the discomfort of being poked and prodded to maintain his life for our sakes. When it was time, we had a fairly peaceful end here at home. On the other hand, with my malo chin, we file as needed, periodically xray and do bloodwork to make sure his kidneys and liver are still ok and keep an eye on him. The difference is that as long as we keep an eye on it, Chilli can still live a normal chinnie life, running around, taking dustbaths, nibbling at my hair, begging for oats. I have always based decisions on quality of life/ expected outcome. Like with Dickens, why subject him to surgery when there was nothing we could do to make it better anyway. A retest of bloodwork two weeks later gave us the same result and was easier on him.
