I did replace his CHE with a radiant heating panal, I believe he know what the weather is even in his house. He has been starting to get up more since the weather is getting warmer. Sammy being in his box for the second day straight yesterday and would not come out of his box, so I had to force him out. He didn't want to be soaked or take a walk, he just wanted to go back in his house to sleep. Hopefully he will want to come out today with the weather getting better.
