Coping with loss of a pet ...?

So sorry about your sweet cat, I know that was a hard decision as I had to make the same decision for my beloved dog after 19 years of companionship. Let go of the guilt, you made the right decision not to let him suffer. I questioned my decision too, but knowing that you made that choice to spare him from suffering just as I did, you have to come to terms with that. It will take time to heal the pain of the loss, I will keep you in my prayers. You did make the right choice, you chose to do what was best for him.
