Looks like Charlie was out drinking with Timmy

That's how my husky sleeps as well

My cat does that too, the back feet straight up.. front paws down. Completely twisted twizzler spine, kinda awful to look at actually.

Chin up = utter contentment and safety

Sometimes I do it myself. It's nice.

Same for my cat, however no cat I've had or known before did it so it's weird to me.

But he seems happy!
