I wish you and your feline friend the best. May you both find peace. I lost my best friend to this a couple years ago now, and something that helped me was the fact that to euthanize is Greek for ‘good death’; is the practice of intentionally ending life to eliminate pain and suffering.

Got to a point where it almost seemed selfish for me to let my buddy go on the way he was, in a state similar to your cats, because it was me who was scared to let go, and I think that’s what kept that final thread attached for so long. It was his time and I was not ready for it, it was a miracle he was still kicking really, but it was not a good existence for my buddy, I had to learn to let go so that he could as well.
