I agree with Deedaa , best to start preparing your son now as his cat has reached a good age. Our previous two cats lived until they were 17 and 21 and like your son's cat, the older one just became increasingly thin and slept a lot. She was in no pain though so the vet checked her regularly and advised us when it was kinder to put to sleep.
