Thank you for that. Our cat died at 16 about seven years ago and that poem fits perfectly. And yes, the tears are coming even after all these years. We gladly paid the vet for whatever they thought might save him until she gently said it was time to let him go. As my wife said we owed it to him to give him whatever chances we could.
