Poor Tyson! That is a heck of a string of bad luck. As for how I'd answer your question, I guess it depends. We don't have children, so while I would stop short of calling our cats our children, we take their companionship and care pretty seriously. (Not implying that those of you with both children and pets do not.) In about 16 years of pet companionship, we've been fortunate to only have the type of dilemma you describe once. Our first cat developed a limp seemingly overnight. We had her looked at the next weekday, and after some ordinary treatments failed, it turned out she had an invasive tumor on her shoulder blade. The options were to amputate (not only the affected front leg but also part of the shoulder blade) or to dull the pain for however long she lasted with meds. She was 10 years old then, so neither a young punk nor really elderly. Knowing what we did about her personality and temperament, our gut reaction was that the proposed operation was too invasive - so we chose the latter course. We did not get too much into what the amputation would have cost. We had incurred a moderate cost (I'd have to look it up but probably in the mid-three-figures) just to figure out that it was cancer, but that was not beyond our means. Our current kitty duo is a heavily bonded pair and I'm not sure how either would cope without the other - so that's a factor I'd want to consider if a big health problem develops with either of them (along with the obvious factors: age, type of problem, prognosis with/without treatment, and cost). There are pet health insurance programs, not without cost but with young(ish) Tyson seemingly being prone to "incidents", maybe that would be worth looking into? Google "pet health insurance" and you will find a wealth (pun unintended) of options. Good luck to you and Tyson.
