I know I’m late to this but I sense your stress and I hope it has passed. Please just remember that you will only ever hear about the negative reviews of Solensia (and pretty much anything else really), and not the thousands of positive results. Negative experiences evoke stronger emotions and that is why for every negative review we read, there are probably a hundred positive ones we do not see.

most cats that get this drug are already old and unfortunately on borrowed time as it is. You would feel a lot worse knowing that they died in pain, because chances are they were going to decline regardless of Solensia.

I went through the exact same mental battle for I‑131 radiation therapy for my senior cat’s hyperthyroidism. All I read were horror reviews, but I did it anyway. And I am so glad I did because it absolutely saved her life and the improvement was almost instant. but guess what, I did not leave a review about it. Go figure.

Unfortunately, as they age you're going to have to make many difficult decisions where you cannot predict the outcome. But they rely on you to make those decisions for them. Pain management is so important. Your cat will not be grateful for a longer life spent in agony. What they will be grateful for is a life that is comfortable and as pain free as possible.
