Bubble and Squeak both love their sleeping bags! They will sometimes sleep on top of them, but mostly in them. They are quite funny though when they are first trying to get comfortable in them.....the bag gets poked and prodded at all angles with their noses, and they make little noises getting cross with themselves until they have got it just right. It's the look on their faces too when they emerge after a snooze and they are full of static!
