What a beautiful story, John.
Thank you for sharing it with us.
I think, you should consider writing books about cats, for kids especially, and publish them. There are so many books about dogs, not too many about cats. I think, the way you put it in words could help little girls and boys understand and love more kitties, so more of those stray kitties could find humans to take them home, like you did with Fister.
Good luck to Fister with all of those unexpected things he gets scared of.
