What a relief that Willow is clear! I know that's a very great relief.
I'm a little unclear, though: is this PKD the run-of-the-mill kidney disease we've heard of for years? Niether my Willie Wonka or Merlin were any of the breeds mentioned. Both were born of barn cats. Willie was a DSH; Merlin was DMH. I suppose, Merlin's hair being medium-long, there might be some Persian in his breeding; anything is possible.

At any rate, the info is very interesting and invaluable to know; thank you for going to the effort of sharing it with us.

Love, Sharon
