The Egg

Sometimes on chilly days (like today), Arthur curls into what we call "The Egg". He brings his back legs forward until they touch his nose, then his front paws go around his back paws and his muzzle and tail are tucked in, creating an aesthetically pleasing ovoid shape.

I've actually never seen him get into this position, so I may have the order all wrong. All I know is that it appears as if by magic.
