Sam loves sleeping on the radiator, especially the one below the window, he can soak up the warmth and look out the window at the same time. And because of our boiler system, there is some warm water circulating through the system all summer. so as long as the air conditioning is on, he's in heaven! Of course I had to get him a nice blanket to use as a radiator cover.
This is a not too old picture, they just love sleeping together any where! We only had the one bed for them at the time this picture was taken, now we have two and they are slowly sleeping in their own beds.
