My maine coon cat of 18+ years passed away from what they believe was a heart attack yesterday evening when I was still asleep, I woke up to find him in his normal sleeping position except with a look of emptiness on his face like he was no longer with us, still kind of in shock to be honest and I don't really know how to convert my feelings like a normal person so I imagine I won't be feeling much until I have fully come out of shock.

He was like the closest thing I had to a friend for almost my entire life and made me happy through so many years since he was basically family, I know so many people do this when there pets die but he was more than a pet to me, was the closest friend I had in my earlier years and I still regret not paying enough attention to him on his last days.
