Ok, I woke up in the middle of the night and Popsie was next to me so I started petting him. Usually when I touch him while he's sleeping he'll raise his head or streatch or do something. Well, this time he didn't move. I messed with his paw which irks him and he still didn't move. So I laid my hand on him and couldn't feel breathing. By now I'm panicking so I turn on the light and sit up. A look at his belly told me he was breathing softly. He was sleeping like a rock. I was totally freaked that he had passed away. That's not the first time Popsie's done that to me either.
