Stimpy sure sleeps deeply. When we first adopted him I would shake him to wake him up to make sure he was ok! I had never had a cat who slept like that. The first couple weeks we had him he slept like he was in a coma or something. I think the month he spent at the shelter he didn't sleep well and was making up for it.
Nabu has nightmares. He will wake from a sound sleep and hiss while looking generally upset.
I think Stimpy dreams of snacking on gerbils.
Raven chases mice or something in his dreams, but like Stimpy doesn't seem to have nightmares.
