I guess if you're rich the money wouldn't matter but for the ordinary person it might not be an option. I really don't know how I would feel about this. I watched human friends and 2 relatives go through chemo and I could barely take the suffering they went through. So to put one of my animals through this suffering would probably mean no, not unless I had a guarantee there would be no suffering. And again, what quality of life would my pet have afterwards? All stuff to consider I think.
