Thank you so much for your kind words. Yes, it has been hard realising that Lightning’s long-term quality of life might be less than what it should be. He is such an adorable cat too.
But at least he’s still with us, I’ve been through the loss of a beloved cat, so I know how painful that can be.
I agree with you about PIP threads, too. I don't post on them myself, they wind me up too much and I really don't want to get into argument, which would be a waste of my time.
