Operate or let nature take its course?
Hi, my 12 year old cat had blood work done that showed possible anemia. They did an x-ray and found a mass on the liver (maybe spleen). The next step is surgery to remove, though they don't know if it can be removed until they look inside. My cat becomes feral when going to the vet, hyperventilates in the car, can't even be removed from the carrier without sedation. My question is this: should I do the surgery or let nature take its course? My hesitation on the surgery is that it will cause weeks of trauma for Sashi, who can't wear a cone or tolerate any kind of treatment, and finds the vet highly aversive. What are the odds that he can live with this mass for some time (he is pain-free, eating, playing) if I chose to do nothing? I want to do what's best for him.
