I had Don Juan microchipped after a sad (if less tragic) case in our area involving a dog which had gotten loose and had been taken to the Humane Society. HS adopted the dog out, and would not rescind the adoption after the original owner found the dog there... leading to a lot of controversy and letters to the newspaper. (Eventually the owner did get the dog back.)

Zerlina was microchipped by Hopalong Animal Rescue, where I adopted her (through a Petsmart adoption center).

Please take comfort in knowing that Kuhio had a good long life with you, and that you honor her in caring for the kitties you have now.
