Oh Lana, you have nothing to feel bad about. That cat was spoiled rotten, and having him PTS was the kindest thing - the only thing - you could have done. It’s a shame it’s not an easier option for humans once they lose all quality of life without the hassle of going to Dignitas.
As for what we’re doing today, Matt apparently spent part of the night snoozing in the laundry bin and has now gone out to enjoy the sunshine. And I woke up to find Socks on my bed. I cannot fill that kitten up. She’s eating me out of house and home. She loves treat sticks - Matt was never bothered.
She’s just run into the room carrying a peg and is delighted with it.
