I’m not sure if it’s mentally healthy to do, but when my kitty was nearing the end I made sure to get some recordings of her purring. I’m so sorry you have to go through this, but it sounds like Zee has had a life full of affection and happiness that you’ve provided for him. He knows you’ll do what’s best for him, and he feels your love. He will always be a happy boy!
